Quick guide to sourcing fasteners

Screws, bolts, nuts, nails, washers and other fasteners, no matter how small, are important in joining materials or parts together. Here are important features importers should check or inquire about to find easily the right product:

Durability – Fastener durability starts from the material to the finish, and according to an IndustryStar blog, it's about strength, corrosion resistance and brittleness.

Buyers should choose fasteners that come in materials that withstand rust to start with, such as stainless steel. If a softer material is preferred but has to have high corrosion resistance, IndustryStar mentions brass and aluminum are usually selected, the former also having a sleek look and the latter for lightweight applications.

As for the finish, zinc or chrome plating and galvanization are among the top surface treatments to look for or request as they are said to enhance corrosion resistance.

Best use – Fasteners aren't just for holding hardware together, they are increasingly being used in decoration, auto parts and machinery as well. In fact, application-specific fasteners, besides durable types, are expected to get high demand as the global market grows through 2025, per a Grand View Research forecast.

Importers stocking up on fasteners for decoration and automotives are better off choosing types that already come in polished finishes or can be custom-made. Examples are screws and rivets that come in a range of colors, shapes and designs such as those trending in design and eCommerce websites – sleek, rainbow, smiley face, pyramid, engraved, vintage and more, serving as accents to vehicle license plates, wooden drawers or cabinets, and the like.

For machinery, buyers should source fasteners that resist harsh environment conditions and provide security, based on a Melfast guide. It is typical for machines to be working on high temperatures or with a lot of vibration, so it makes sense the fasteners suitable for them are heavy-duty enough to last in these situations. Melfast also adds that because machines are operated only by authorized personnel with the expertise, they have to be secure against tampering, and fasteners help with this. Machine screws, for instance, can have custom head shapes that do not match common screwdrivers. A Zoro article lists Torx, one-way, spanner, tri-groove and hex as tamper-resistant head design options for machine screws.

Fit – Fasteners are usually offered in a range of lengths, diameters, tread sizes and head shapes, and in buying or sourcing, importers must go beyond just simply picking out a range. Whether the size fits the application also factors in. Are fasteners of a certain size range able to go through or hold together what material thickness? Up to what weight can they bear depending on their size? These matter when sourcing screws, for example, because the bigger the screw diameter and the longer the length is, the more the fastener becomes tear- and force-resistant, based on a ManoMano guide.
