The HOLO-KROME 88348 is a button head socket cap screw designed for applications requiring a low-profile fastening solution with a clean finished appearance. This fully threaded screw features an 8-32 UNC thread form and a 3/32-inch hex socket drive, machined from alloy steel with a black oxide finish for corrosion resistance. At 1 inch in length under head and a head diameter of 0.312 inches, it delivers a compact profile suitable for tight clearance assemblies. With a hardness rating of 38 HRC and a 3A thread fit class, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. Installed by machinists, maintenance technicians, and mechanical contractors across a wide range of industrial and equipment assembly applications.
The HOLO-KROME 88348 is suited for use in light machinery, enclosures, fixtures, and mechanical assemblies where a flush or low-profile fastener head is required. The black oxide finish provides mild corrosion resistance in dry or lightly humid indoor environments. The right-hand, fully threaded 8-32 UNC configuration makes it compatible with standard tapped holes and threaded inserts commonly found in aluminum, steel, and plastic components across industrial and commercial equipment manufacturing.
Designed as an OEM-style replacement or standard production fastener for any application requiring an 8-32 UNC button head socket cap screw with a 1-inch length under head, conforming to ANSI/ASME B18.3 dimensional standards.
Installation is performed using a 3/32-inch hex key or Allen wrench; confirm the mating tapped hole meets 8-32 UNC thread standards before driving. Power down any equipment fully before accessing fastener locations on live machinery. Avoid over-torquing into soft base materials such as aluminum or plastic, as the 38 HRC alloy steel screw can strip softer threads. Follow applicable ASME or equipment manufacturer torque guidelines for the specific joint material and clamp load requirement.
