Value Collection 97066 Hex Head Cap Screw 3/8-16 X 4 in Grade 5

Product Description

The VALUE COLLECTION 97066 is a 3/8-16 hex head cap screw designed for general mechanical assembly and structural fastening applications. Manufactured from Grade 5 steel with a bright uncoated finish, this fastener measures 4 inches under the head with a 3/8-16 UNC thread form and partial threading along the shank. Partial threading provides a smooth shank section that resists lateral shear loads, making it well suited for bolted joints that see both tension and shear. This screw conforms to ASME B18.2.1 dimensional standards and is driven with a 9/16-inch hex wrench or socket. Sold in a package quantity of 25.

This cap screw is used across a wide range of trade applications including HVAC equipment mounting, mechanical room installations, structural steel connections, panel and bracket assemblies, and general maintenance work. Its inch-series UNC thread and Grade 5 steel construction make it a common choice for equipment framework, pump and motor mounting bases, and field fabrication where a standard-strength fastener meeting ASME B18.2.1 is required.

Designed as a standard inch-series hex head cap screw for use in any application requiring a 3/8-16 UNC threaded fastener with a 4-inch grip length and Grade 5 steel strength rating.

Installation Notes

Installation is performed with a 9/16-inch hex socket or open-end wrench. A properly sized and tapped or through-drilled hole with a standard UNC nut or tapped thread is required before installation. Verify fastener grade requirements against the equipment manufacturer specifications before substituting fasteners in structural or pressure-bearing assemblies. Follow applicable mechanical codes and torque guidelines for 3/8-16 Grade 5 fasteners as specified by the equipment OEM or relevant industry standards.
