1/4-20 x 5/16 18-8 Stainless Steel Low Head Socket Cap Screw provides a reduced-head socket-drive option for assemblies that need stainless construction and controlled head projection.

The low head geometry gives this 1/4-20 x 5/16 fastener a reduced profile for robotics and automation equipment, where compact socket-head geometry supports tight machine envelopes and serviceable internal-hex installation. It may also be specified for conveyor systems and packaging equipment, where lower head projection can reduce snag points while still providing socket-drive access for maintenance.

18-8 stainless steel is a general-purpose stainless choice for indoor equipment, many outdoor installations, and assemblies where a clean appearance is important.

Cold Headers serves machine builders, repair operations, and industrial distributors that need exact-size socket screws without exaggerated inventory claims.
