The VALUE COLLECTION 99052 is a fully threaded hex head cap screw designed for general-purpose mechanical fastening in structural and industrial applications. Manufactured from Grade 8 steel with no finish coating applied, this fastener delivers high tensile strength suitable for demanding bolted connections. The 3/8-16 thread size follows the Unified National Coarse (UNC) standard, and the 3/4-inch length under head ensures consistent clamping in standard through-hole and tapped assemblies. This screw conforms to ASME B18.2.1, the governing dimensional standard for inch-series hex cap screws. Sold in a pack of 100 units, it suits contractors, maintenance crews, and mechanical shops stocking common fastener sizes.
This hex head cap screw is used across a wide range of residential and commercial mechanical, HVAC, plumbing, and general construction applications wherever a high-strength inch-series fastener is required. The UNC 3/8-16 thread pattern is one of the most common coarse-thread sizes encountered in equipment assembly, equipment mounting brackets, structural connections, and field repairs. The uncoated finish is appropriate for indoor or protected installations where corrosion exposure is not a primary concern. Trades including HVAC technicians, pipefitters, electricians, and general maintenance personnel commonly use this size for panel mounting, equipment bases, and mechanical supports.
Designed as an OEM-style and general-replacement hex head cap screw for any application requiring a 3/8-16 UNC fully threaded fastener with a 3/4-inch length under head conforming to ASME B18.2.1.
Installation is performed with a standard hex wrench or socket driver sized for a 3/8-16 hex cap screw head. Always verify the mating thread size and pitch before installation to avoid cross-threading. For structural or load-bearing applications, consult applicable building or mechanical codes for required torque and fastener grade specifications. Grade 8 fasteners should not be substituted with lower-grade hardware in safety-critical joints without engineering review.
