7/8-9 x 3 3/4 Alloy Steel Socket Head Cap Screw gives engineers an internal-hex fastener for mechanical joints where socket engagement and dimensional consistency matter. The size callout supports replacement sourcing without changing the specified size when tooling plates cannot accept a substitute fastener. Industrial buyers may specify it for industrial facilities, automation systems, and maintenance repair where head geometry and drive access need to be predictable. Socket engagement helps technicians apply installation torque from above the head in constrained layouts. The technical highlight block below retains the verified head diameter, head height, body diameter, and hex key data. Technical Highlights Material: Alloy Steel Thread: 7/8-9 Length: 3 3/4 in.

Head Diameter: 1.293 in. min / 1.312 in. max Head Height: 0.864 in. min / 0.875 in. max Hex Key Size: 3/4 Drive Type: Internal hex socket Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.
