Alloy Steel Socket Head Cap Screws

Open up any modern machine tool, fixture, or automation cell and count the fasteners: the alloy steel socket head cap screw outnumbers everything else, and there's an engineering reason for it. A hex head bolt needs a wrench swung around it — which means every hex bolt on a design demands empty space that could have been used for something. A socket head cap screw wrenches from above, straight down its own axis. That one difference lets designers put screws at the bottom of pockets, space them closer together, and sink them flush into counterbores where nothing snags, catches chips, or interferes with a moving part. The compact cylindrical head isn't a style choice; it's what makes dense, clean machine design possible.

Strength closes the argument. Alloy steel socket head cap screws are the strongest standard screw you can buy off a shelf — stronger than a Grade 8 hex bolt — which means a designer can spec a smaller diameter for the same clamp load, and the smaller screw needs a smaller counterbore, which buys back even more room. Machine building, tooling and fixture construction, dies, automation systems, material handling equipment, and precision assemblies all run on that math, and maintenance departments keep these screws in the crib because the deep, crisp hex socket survives repeated service without rounding.

Our online catalog includes many commonly requested alloy steel socket head cap screw sizes, but it does not represent every configuration we can supply. Non-catalog diameters, special lengths, and difficult-to-source items are quoted every week — it's much of what we do.

If the exact alloy steel socket head cap screw required for your application is not shown, there is a good chance we can still quote or supply it.

Description N/A 0-80 x 1/16 Alloy Steel Socket Head Cap Screw fills a length step between the common catalog sizes of this thread. The socket head form drives with an internal hex, allowing installation in counterbored and shielded locations where an external wrench cannot swing. Alloy steel construction gives the high tensile strength expected of socket head cap screws, appropriate for clamping structural and machine joints. Uncommon sizes in this range are confirmed for availability when ordered. Pricing is quoted per 100 pieces; contact us for current pricing and availability on this size. If a nearby length or a modified version (point styles, tips, thread variations) is needed, ask — modification work is done on site. Orders are packaged and labeled for industrial stockroom use. The size is listed exactly as dimensioned so search and drawing callouts match one to one. Distributors and OEM purchasing teams can reference this exact size for repeat orders. The size is listed exactly as dimensioned so search and drawing callouts match one to one. Technical Highlights Material: Alloy Steel Thread: 0-80 Length: 1/16 in. Nominal Body Diameter: .060 in.
