Use the 6-32 x 5/16 18-8 stainless hex head cap screw when the assembly calls for side wrench access and a general-purpose bolt pattern. In this size range it is treated as a hex head machine screw, with the hex head driven by external tooling rather than an internal socket.
Common application reviews include machinery guards, side-mounted brackets, and serviceable equipment joints. External hex drive is useful when a wrench or socket can reach the head from the side and a counterbore would add unnecessary machining.
18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material used for ordinary atmosphere, moisture exposure, washdown, and clean appearance. Cold Headers' catalog work is strongest where the requested size, material, and application details need a careful match.
