1/4-28 x 6 18-8 Stainless Steel Hex Head Cap Screw provides a familiar wrench-driven head for plant equipment and field replacement work. In this size range it is treated as a hex head cap screw, with the hex head driven by external tooling rather than an internal socket.

Common application reviews include food processing skids, washdown equipment, and packaging lines. The head can be tightened with standard side-access tooling, which helps where top clearance is limited by covers or nearby components.

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 helps buyers match uncommon lengths, older drawings, and replacement sizes without changing the protected SKU data.
