This Harfington review compares hardware, repair parts, pack sizes, shipping costs and return rules to help you check fit before placing a DIY parts order.
Harfington is an online supplier of hardware, tools and small replacement components. Its catalog covers fasteners, electrical accessories, fittings, power-transmission parts, automotive items and hobby supplies. The attraction is breadth: a small component that is difficult to identify locally may appear in several dimensions or pack sizes. The challenge is that a visually similar part can still be the wrong specification.
This is a research-based store review, not a hands-on load, electrical or material test. We have not independently measured manufacturing tolerances, verified every alloy or tested the service life of a purchased item. Dealnory may earn commission from affiliate links.

What is Harfington useful for?
The catalog suits buyers who can identify a component by its technical details. Examples in the reviewed Uxcell collection included M8x1.25mm T nuts, a DB25 ribbon cable and short T8 lead screws with nuts. These are specific parts, not interchangeable general-purpose substitutes. Search terms that include dimensions, connector type and material usually provide a more meaningful comparison than a broad phrase such as furniture screw.
It can also be useful for planned hobby projects where you know the required specification and can wait for delivery. It is less convenient for a repair that must be completed immediately or where a missing original specification makes compatibility uncertain. In those situations, access to a qualified technician or a local counter that can inspect the original part may matter more than a lower catalog price.
Check dimensions beyond the headline number
For a threaded part, nominal diameter is only one detail. Thread pitch, length, head style, direction and the intended mating component also matter. A product photograph cannot show all of them reliably. Compare the written specifications and dimension diagram with the original part or design drawing. Do not infer a thread standard from appearance or from a title that lists only the largest measurement.
For a bearing or bushing, record the required inner diameter, outer diameter and width. For tubing and fittings, distinguish inside and outside dimensions and confirm the relevant connection standard. Measure carefully with appropriate tools and use consistent units. If the drawing, title and selectable variant disagree, ask support which specification will actually be supplied before ordering.
Pack sizes and unit cost
The reviewed collection displayed a 30-piece M8x1.25mm T-nut pack at $8.67, a DB25 male-to-female ribbon cable at $8.63 and a two-piece short lead-screw listing at $12.14. These were observed US-dollar catalog prices, not guaranteed checkout quotes. They illustrate why quantity matters: a pack price should not be compared directly with the price of one individual component.
Calculate the cost per usable piece, including delivery, and consider whether you will use the remainder. Buying a larger pack solely to cross a shipping threshold can leave you with unnecessary stock. Conversely, a small spare quantity may be useful for a repeated hobby project. Confirm whether the listing counts complete sets, individual screws or a mixture of components.
Materials and application limits
Read material and finish descriptions separately. Zinc plating describes a surface treatment; it does not establish that the underlying part is stainless steel. An alloy name also does not establish every strength, corrosion or temperature characteristic needed for a project. Ask for the applicable technical documentation when the use depends on a particular specification.
For automotive parts, verify the exact vehicle configuration and part reference. For electrical items, match the approved voltage, current, connector arrangement and intended environment. A connector that physically fits can still have an incompatible pin assignment. Product photography is not enough to establish suitability for a mains circuit, safety system or other demanding application. Use qualified help where the application requires it.
Shipping: compare the destination-specific table
The US shipping table reviewed listed standard transit of six to sixteen days, with a $3.99 charge below $30 and free standard shipping above $30. Processing of one to two days is additional. The threshold wording leaves an order priced exactly at $30 unclear, so use the actual checkout quote. Remote-area charges and address restrictions can also affect eligibility.
The policy has separate tables for other countries and shipping methods. Do not copy the US threshold to a UK, European or Canadian order. Express delivery may have different tax and duty treatment. Check the selected destination, delivery method and final charges together. An express option is only useful when the item itself can be dispatched promptly.
The shipping page says out-of-stock quantities can take longer to dispatch and that mixed orders are generally consolidated. If one component is urgent, ask whether it will be held for another item. Compare the total time from order to arrival, including processing and stock availability, rather than relying only on the shortest transit estimate in a table.
Returns: resolve fit before installation
The return policy reviewed gives a 30-day window and generally requires original packaging, intact product identifiers, accessories and documentation, with parts in new, uninstalled condition. Tool marks or installation can make a return unacceptable. Contact support for authorization and the correct warehouse address before sending anything back; the address on the original parcel may not be the return destination.
Free-return wording is inconsistent between the summary table and detailed regional clauses, including different European thresholds. Ask for the actual postage allocation for your item and location. Do not assume a low-priced order automatically receives a prepaid return. The policy also distinguishes incorrect fit selection from a defective item, which makes pre-purchase verification important.
It lists a standard 365-day warranty for eligible products unless otherwise specified, covering manufacturing defects under intended use. That is different from a change-of-mind return and does not make a part suitable for any installation. Save the item specification and order record. Wholesale and custom orders have separate restrictions, so obtain those terms before placing a business quantity.
A practical ordering method
Build a short parts list containing the item reference, required dimensions, material, quantity and application. Check each selected variant against that list before payment. Keep a copy of the product description and any written clarification. This is particularly useful when several nearly identical options share photographs or when you may need the same part again later.
On arrival, compare the supplied quantity and identifying details with the order before opening every bag or installing anything. Keep similar components separated and labeled. If there is a mismatch, take clear photographs and contact support promptly. Avoid modifying a part while still deciding whether it is the correct item; that can complicate both troubleshooting and return eligibility.
Is Harfington worth considering?
Harfington is worth comparing for planned DIY and repair purchases when you can specify the correct part and allow for international-style delivery timelines. Its wide assortment and multiple pack sizes can be useful. The limitations are the work needed to verify compatibility, possible shipping delays for mixed stock and return restrictions after installation. The cheapest visually similar item is not necessarily the lowest-cost successful repair.
Confirm specifications, pack count, stock, delivered total and return postage before ordering.

The cover shows examples from the official catalog in an editorial workbench setting; it is not evidence that we installed or tested those parts.
