0-80 x 5/16 Alloy Steel Button Head Socket Cap Screw gives equipment builders a rounded button-head form for visible or frequently handled fastening points. The alloy steel construction is appropriate for tooling applications that require a smooth exposed appearance with internal hex engagement.
This configuration is practical for machine covers and service panels where the finished head appearance is useful on exposed equipment. It also works in control enclosures and equipment housings when the rounded head reduces sharp edges on handled surfaces. The button-head form is specified when the fastener head remains visible or accessible and a smooth rounded profile is preferred.
For assemblies specified with 0-80 thread and 5/16 in. length, the reference head diameter is 0.104-0.114 in. and the head height is 0.026-0.032 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.
