Holo-krome 60068 Flat Socket Cap Screw 1/4-20 X 1-1/2 in

Product Description

The HOLO-KROME 60068 is a flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features an 82-degree flat head with a 5/32-inch hex socket drive, giving technicians positive torque transfer with standard hex keys. The screw is manufactured from alloy steel with a black oxide finish and carries a hardness rating of 39-44 HRC, making it suitable for high-stress assemblies. The 1/4-20 UNC thread is fully threaded along the 1-1/2-inch overall length, conforming to ASME B18.3 and ASTM F835 standards. Thread fit class is 3A. Installers in industrial maintenance, mechanical assembly, and HVAC equipment fabrication commonly use this fastener when a flush surface is required.

This flat socket cap screw fits residential and commercial assembly applications where countersunk fastening is specified. It is well suited for equipment panels, brackets, and machinery frames that require a flush or recessed fastener profile. The 1/4-20 UNC thread is one of the most common inch-series thread sizes, making it a standard replacement or stocking item for maintenance shops, mechanical contractors, and OEM assembly operations. Minimum order quantity is 100 pieces per order.
