1/4-28 x 7/8 18-8 Stainless Steel Low Head Socket Cap Screw is built for compact fastening locations where thread engagement, length selection, and head clearance all matter.

Cold Headers has supplied specialty socket fasteners since 1962, helping purchasing teams source exact sizes for industrial maintenance and production work.

The low head geometry gives this 1/4-28 x 7/8 fastener a reduced profile for electrical enclosures and control panels, where the low head design helps keep hardware projection controlled on exposed or space-limited surfaces. It may also be specified for instrumentation and precision machinery, where the clean stainless appearance and compact head style support equipment where clearance and access both matter.

The 18-8 stainless steel material is commonly chosen for general corrosion resistance, clean appearance, and routine moisture exposure in common industrial environments.
