1/4-28 x 1 1/2 18-8 Stainless Steel Low Head Socket Cap Screw supports compact equipment layouts that call for a low-profile socket screw in 18-8 stainless steel.

The low head geometry gives this 1/4-28 x 1 1/2 fastener a reduced profile for instrumentation and precision machinery, where the clean stainless appearance and compact head style support equipment where clearance and access both matter. It may also be specified for machine guards and access panels, where the reduced head profile helps prevent interference around removable covers and moving components.

For many plant, automation, and packaging environments, 18-8 stainless steel offers a practical balance of corrosion resistance and broad industrial usability.

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