Value Collection 99018 Hex Head Cap Screw 1/4-20 X 5 in Grade 8

Product Description

The VALUE COLLECTION 99018 is a 1/4-20 hex head cap screw designed for general mechanical and structural fastening applications. This fastener measures 5 inches in length under head with partial threading and is manufactured from Grade 8 steel in an uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding fastening requirements. It conforms to ASME B18.2.1, the standard governing inch-series hex cap screws. This screw is driven with a standard hex wrench or socket and is intended for installation by machinists, millwrights, maintenance technicians, and general tradespeople working with Unified National Coarse thread fasteners.

This hex head cap screw is used across a wide range of industrial, mechanical, and trade applications including equipment mounting, structural assemblies, and machinery maintenance. The 1/4-20 UNC thread pattern is among the most common inch-series thread specifications in North American mechanical systems. Partial threading is standard for longer-length fasteners at this diameter and provides a clean shank section useful in applications requiring precise hole alignment or shear loading. Sold in a package quantity of 50 per order.
