Returns & Refunds Policy
At Harrowfast, we want you to shop with confidence when ordering bolts, brackets, anchors, drill bits, braces, and fixing accessories from harrowfast.com. This policy sets out our voluntary 30-day return arrangements alongside your statutory rights under UK consumer law.
Return & Refund Policy Overview
- Voluntary Return Window: 30 calendar days from the day after delivery
- Return Shipping Cost: Free (£0.00) for eligible returns using the enclosed prepaid return label
- Restocking / Administration Fee: None (£0.00)
- Return Method: By Mail (using the pre-printed prepaid return label included in your parcel)
- Accepted Condition (Change-of-Mind): Brand-new, unused, uninstalled condition in original packaging (complete sets with undamaged threads)
- Refund Processing Time: Inspection and refund completed within 3 business days of receiving the returned parcel (in GBP £ to original Visa or Mastercard)
1. Return Window and Statutory Rights
Our voluntary return policy allows eligible items to be returned within 30 calendar days from the day after delivery for a refund, subject to the applicable conditions stated in this policy.
This voluntary policy is separate from your statutory cancellation rights (including your 14-day cooling-off rights under the Consumer Contracts Regulations 2013) and your rights relating to faulty, damaged or misdescribed goods under the Consumer Rights Act 2015. Nothing in this policy excludes or restricts your statutory rights under applicable UK consumer law.
2. Condition of Returned Items (Building Hardware Inspection Guidelines)
For change-of-mind returns under our voluntary 30-day policy, fasteners, brackets, drill bits and small parts should be returned in brand-new, unused and uninstalled condition, complete in their original protective packaging with all pieces, compartments, and labels intact:
- Uninstalled & Thread-Intact Standards: Bolts, nuts, and anchor sleeves must not have been tightened with high-torque spanners, driven into masonry or timber, cross-threaded, stripped, or rounded off. Items must be completely free from outdoor rust, grease, cement dust, mortar stains, or tool marks on screw heads and bracket finishes.
- Drill Bit Sets & Multi-Packs: Drill bits must be completely unsharpened, unused, and free from tip heat discolouration, chipping, or flute residue. Fastener sets (such as Nut & Bolt Sets or Grommet packs) sold in multi-piece boxes must be returned as full, complete sets rather than partial packs with missing hardware.
- Reasonable Inspection Allowed: In accordance with UK consumer law, you may open the outer box indoors to inspect the thread diameter, bracket gauge, finish, and dimensions to establish the nature, characteristics and functioning of the hardware, as you would examine items in a trade shop. Where applicable law permits, we may make a proportionate deduction for any reduction in value caused by handling beyond what is reasonably necessary.
These condition requirements do not override statutory rights relating to cancellation, faulty goods, damage or items that do not match their description.
3. Return Costs and Fees
Return shipping is free (£0.00) for eligible returns using the prepaid return label supplied with your order. If the original label is unavailable, contact our customer support team for a replacement PDF label at no cost.
We do not charge restocking, administration or return postage fees for eligible returns. Any deduction for a reduction in value will only be made where permitted by applicable law.
4. How to Return Your Item by Mail
Returns are handled by mail using the pre-printed, prepaid return shipping label enclosed inside your parcel:
- Step 1 – Repack Carefully: Place all unused fasteners, brackets, drill bits and accessories securely back into their original manufacturer packaging. Ensure heavy metal components are cushioned so they do not puncture outer cartons during transit, and enclose your packing slip or order number.
- Step 2 – Attach the Prepaid Return Label: Affix the prepaid return shipping label (included inside your package, or provided as a free PDF replacement by our support team) flat across the exterior of the parcel, covering the original delivery barcode.
- Step 3 – Post Your Parcel: Drop the sealed parcel off at the designated local Post Office branch or authorised carrier drop-off point indicated on the label, and retain your proof-of-postage receipt.

We will arrange an appropriate resolution at no cost to you, including a replacement or full refund in accordance with our stated policy and applicable consumer law.

For eligible returns, we will complete our inspection and issue the refund within 3 business days of receiving the returned parcel.

If you wish to amend or cancel your order, please contact us as soon as possible at support@harrowfast.com or +44 20 8960 1544. We can amend the delivery address or cancel the order where it has not yet entered a stage that prevents the requested change. If cancellation is accepted, we will arrange the applicable refund to your original payment method. Statutory cancellation rights remain unaffected.
Category 2: Delivery & Shipping Rates
4. How much is delivery, and how do I qualify for free shipping?
Delivery is free (£0.00) on all UK orders where the product subtotal is £100.00 or more. For orders under £100.00, standard tracked UK delivery is charged at a flat rate of £10.00 across all UK postcodes.
5. How long will my order take to arrive?
Orders placed before 2:00 PM UK local time (GMT/BST), Monday to Friday, enter our processing queue on the same working day. Our handling time is 1–3 business days (Monday to Friday) and estimated carrier transit time is 3–5 business days (Monday to Friday), giving an estimated total delivery timeframe of 4–8 business days.
Orders placed after 2:00 PM UK local time, or on weekends or UK bank holidays, begin processing on the next working day. The 4–8 business-day delivery timeframe is an estimate calculated from the applicable processing start date and excludes weekends and UK bank holidays. Delivery dates are not guaranteed.
6. Will I receive tracking information?
Yes. When your parcel leaves our dispatch facility, we will send a dispatch confirmation email containing the carrier name, tracking number and a direct tracking link.
Category 3: Hardware & Fastener Specifications
7. Are your bolts and nuts manufactured to metric thread standards?
Yes. The majority of our bolts, nuts, and machine screws follow standard ISO metric coarse thread profiles (such as M4, M5, M6, M8, M10, and M12). Please check the individual product listing for specific thread diameters, thread pitches, and length measurements.
8. How do I choose the correct wall anchor for my wall type?
Choosing the correct anchor depends on your substrate. For solid brickwork and dense concrete, use our heavy-duty steel expansion anchors or nylon expansion plugs. For hollow plasterboard stud walls, use specialized hollow-wall cavity anchors or spring toggles to distribute the clamping load across the rear face of the plasterboard. Check the individual product description for substrate suitability and minimum hole depths.
9. What corrosion protection is applied to your brackets and braces?
Depending on the model, our corner braces and brackets are finished with bright zinc plating (BZP), hot-dip galvanising, electro-galvanised passivate, or black powder coating to resist indoor and sheltered atmospheric corrosion. For marine or exposed coastal exterior use, marine-grade A4 stainless steel fixings are recommended where specified.
10. What materials are your Drill Bit Sets suitable for?
Our HSS twist drill bits are designed for mild steel, non-ferrous metals, timber, and plastics, while our carbide-tipped masonry bits are specifically engineered for brick, masonry, and stone drilling with rotary or hammer drills. Always match the drill speed to the material being bored and use coolant on dense metals to preserve bit sharpness.
Category 4: Returns & Refunds
11. What is your return policy, and is return shipping free?
We offer free returns for eligible items under our voluntary 30-day return policy. The return period runs for 30 calendar days from the day after delivery. For change-of-mind returns under this policy, building hardware should be returned unused, uninstalled, clean and complete in its original packaging. Each parcel includes a pre-printed, prepaid return label.
This voluntary policy is separate from your statutory cancellation rights and your rights relating to faulty, damaged or misdescribed goods. Nothing in this policy limits your statutory rights under applicable UK consumer law. Return postage, restocking and administration fees are not charged for eligible returns. Any deduction for reduced value will only be made where permitted by law.
12. How quickly will my refund be processed?
For eligible returns, we will inspect the returned item and issue your refund within 3 business days of receiving it at our returns facility. Where statutory cancellation rights apply, we will comply with the applicable legal refund deadlines, including where proof that the goods have been sent back triggers an earlier deadline. Refunds are issued to your original Visa or Mastercard payment method in GBP (£). Your card issuer may require additional time to display the funds in your account.
