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 1/4-20 x 11/32 Alloy Steel Socket Head Cap Screw supports fixture and tooling work where the specified grip stack requires an non-catalog increment. It is useful for spacer stacks, repair plates, and compact machine frames, especially when the 1/4-20 thread and 11/32 in. length must match existing parts rather than a nearby standard size. Reviewing the verified head dimensions helps avoid conflicts with counterbores, covers, and adjacent machine surfaces. The page supports exact-size searches, purchase review, and maintenance matching without unsupported claims. Use the callout and highlights to confirm the part before requesting pricing and availability. Technical Highlights Material: Alloy Steel Thread: 1/4-20 UNC Length: 11/32 in. Nominal Body Diameter: .250 in. Head Diameter: 0.365 in. min / 0.375 in. max Head Height: 0.244 in. min / 0.250 in. max Hex Key Size: 3/16 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote. N/A 1/4-20 x 13/32 Alloy Steel Socket Head Cap Screw is built into this expansion for buyers matching legacy equipment to an uncommon length. It is useful for legacy equipment, jigs, and maintenance replacement points, especially when the 1/4-20 thread and 13/32 in. length must match existing parts rather than a nearby standard size. The listing keeps thread, length, body diameter, head size, and drive information together for purchasing review.

N/A 1/4-20 x 1 1/16 Alloy Steel Socket Head Cap Screw gives procurement a searchable alloy steel socket screw listing for an odd length. It is useful for MRO repairs, drawing-controlled joints, and machinery rebuilds, especially when the 1/4-20 thread and 1 1/16 in. length must match existing parts rather than a nearby standard size. The cylindrical socket head works with counterbored pockets where head diameter, head height, and key size have to be checked before ordering.
