12-28 x 7/8 Alloy Steel Button Head Socket Cap Screw fits applications where engineers want socket drive control in a rounded head rather than an external wrenching feature. The alloy steel construction is appropriate for tooling applications that require a smooth exposed appearance with internal hex engagement.
Frequent uses include control enclosures and equipment housings where the rounded head reduces sharp edges on handled surfaces. It is also practical in robotics and packaging machinery when internal hex drive access supports repeatable assembly work in tight spaces. This head style is different from a standard socket head cap screw: it trades the taller cylindrical head form for a rounded button profile used on exposed assemblies.
For assemblies specified with 12-28 thread and 7/8 in. length, the reference head diameter is 0.383-0.413 in. and the head height is 0.104-0.117 in. The nominal body diameter and hex-key information below help maintenance and purchasing teams verify fit and tool access.
Reference dimensions may vary slightly by manufacturer.
