The VALUE COLLECTION 99488 is a 3/8-24 UNF hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel in an uncoated finish, this partially threaded fastener measures 2 inches under the head and meets ASME B18.2.1 dimensional standards. Grade 8 steel delivers a tensile strength rating suited for demanding mechanical and structural assemblies where fastener integrity is critical. The hex drive head accepts standard hex wrenches and sockets, making installation straightforward for maintenance technicians, pipefitters, electricians, and general tradespeople working with metal assemblies, equipment frames, or structural components.
This cap screw is appropriate for use in mechanical assemblies, equipment mounting, structural connections, and general industrial fastening where a fine-thread UNF pattern is specified. The 3/8-24 fine thread pitch provides greater thread engagement per inch compared to coarse thread, making it well suited for applications requiring precise torque control or resistance to vibration loosening. Partial threading leaves a smooth shank section under the head, which helps resist shear loads in bolted joint applications. Sold in a package quantity of 50 fasteners.
Designed as a standard UNF hex head cap screw suitable for any application specifying a 3/8-24 x 2-inch Grade 8 partially threaded fastener conforming to ASME B18.2.1.
Installation should be performed by a qualified technician familiar with fastener torque specifications for Grade 8 hardware. Always consult the equipment manufacturer or applicable engineering specification for required torque values before installation. Use the correct hex socket or wrench size to avoid rounding the head. Inspect mating threads for damage or contamination prior to assembly to ensure full thread engagement.
