4-40 x 2 1/4 Alloy Steel Socket Head Cap Screw is commonly used where an Allen-style socket drive is preferred over external-wrench hardware in confined equipment layouts. The 4-40 thread and 2 1/4 in. length support service work where the exact thread and length are already defined in production-floor assemblies. Industrial buyers may specify it for maintenance shops, engineering departments, and production lines where head geometry and drive access need to be predictable. The socket head form provides a cylindrical head suited to counterbores and recessed mounting pockets. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 4-40 Length: 2 1/4 in.

Head Diameter: 0.176 in. min / 0.183 in. max Head Height: 0.108 in. min / 0.112 in. max Hex Key Size: 3/32 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.
