Whatever project you are working on, it likely will require that materials be secured together. When numerous materials are involved, contractors and builders need versatility, and socket screws can be the perfect fasteners to finish the job. Screw sockets come in a range of thread sizes, cap head styles, and lengths, so you can match the fastener to the job. Fastener SuperStore offers a wide selection of bulk sockets, Allen wrenches, set screws and more for every application. Let our dedicated staff help you decide on the right sockets screws for your project, or browse through our socket categories to find what your project needs.

Socket Solutions for Every Application

Many of our socket products are stainless steel, or alloy steel with a black oxide or zinc finish. They are available with coarse or fine thread options, as well as in metric sizes.

Socket head cap screws have a smaller head with a hexagonal drive. They often are used with machine parts where there is limited space for wrenches, as they are driven in with a hex key. Socket head screws provide a stronger hold than conventional screws.
Button head socket cap screws have a round button head and are ideal for light-duty applications and clamping due to their tensile strength.
Flat head socket cap screws are used in applications where the screw head will sit flush with the surface. They provide a cleaner finish, as the flat top can be covered and thus not visible.
Low head socket cap screws have a shorter, round head, and can be used in tighter spaces where head height would be an issue. They have a high tensile strength yet should not be used in projects that experience dynamic loads.
Metric sockets are available for when hardware with metric measurements is required. Available products include socket head cap screws, button head socket cap screws, flat head socket cap screws, hex keys and socket set screws.
Socket shoulder screws, also called “stripper bolts,” are commonly used in machine designs that allow parts to oscillate and pivot. These screws can be used in punch and die applications.
Socket set screws do not have a head cap and can sit flush or imbedded into the materials. They are available with flat, cup, cone or pointed heads.
Socket pipe plugs are ideal when closing the end on fittings and pipes. They have a low profile to fit into tight spaces.
Hex keys/Allen wrenches are small, manual wrenches used on hex key sockets to drive in screws. They also are available in sets to provide a range of short-arm and long-arm wrenches that will fit a variety of sockets.

Frequently Asked Questions:

What materials are socket fasteners made from?

Socket fasteners are commonly made from alloy steel for strength and consistent performance, with stainless steel options available when corrosion resistance matters. Many socket head screws also come with protective finishes. Material choices are typically aligned with industry standards for strength, hardness, and fit.

Where are socket fasteners typically used?

You’ll find socket fasteners in machinery, equipment assembly, automotive work, and tight-clearance builds where a cylindrical head makes sense. They’re also popular in industrial maintenance because they can handle high torque and stay secure in applications that see vibration and repeated service.

How do socket fasteners differ from standard screws?

Socket fasteners use an internal drive, so the tool engages fully on the inside of the head instead of on the outside like a hex head screw. That design supports more torque without cam-out, and the head shape can fit neatly in recessed or tight spaces.

What tools are required to install socket screws?

Most socket screws are installed with a hex wrench, sometimes called an Allen key. For higher torque jobs, many installers use a hex bit socket on a ratchet or torque wrench to get consistent tightening without stripping the drive. Match the tool size to the fastener.

Do socket screws come in bulk quantities?

Yes. Socket screws are often available in box and case quantities for shops and production needs. If you’re ordering for a crew or assembly line, wholesale socket screw options help keep common sizes in stock and make reordering simpler across ongoing projects.
