Value Collection -30165-3 Hex Head Cap Screw 7/8-9x3 G5

Product Description

The VALUE COLLECTION -30165-3 is a hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener measures 7/8-9 thread size with a 3-inch length under the head. The partial threading is consistent with standard hex cap screw geometry, allowing the unthreaded shank to bear shear loads in bolted joints. Licensed mechanical contractors, millwrights, and maintenance technicians install this type of fastener across a wide range of structural and equipment assembly tasks. It conforms to ASME B18.2.1, the accepted dimensional standard for inch-series hex cap screws in North American trade work.

This fastener is suited for bolted connections in steel fabrication, mechanical equipment mounting, and general structural assembly where Grade 5 strength and corrosion-resistant zinc plating are specified. The 7/8-9 UNC thread is a coarse-pitch designation common in heavy mechanical and industrial settings. Partial threading leaves a full-diameter shank beneath the head, which is preferred in applications where the bolt passes through a clearance hole and the joint relies on clamping force rather than thread engagement throughout the full grip length. Typically sold in packages of 25 units.

Key Features

• Grade 5 steel construction for mid-range tensile strength in structural fastening
• Zinc-plated finish provides baseline corrosion resistance for indoor and moderately exposed installations
• Partially threaded shank suited for shear-load and clearance-hole bolted joints
• 7/8-9 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standard for inch-series hex cap screws
• Sold in 25-unit packages to support job-site quantities

Compatibility

Designed as a standard inch-series hex cap screw for use with 7/8-9 UNC nuts, washers, and tapped holes conforming to ASME B18.2.1 specifications in general mechanical and structural assemblies.

Installation Notes

Installation is performed by licensed mechanics, millwrights, or qualified maintenance personnel using standard hex wrenches or impact sockets sized for 7/8-9 fasteners. Always degrease mating surfaces and inspect threads for damage before assembly. Torque to the value specified in the applicable engineering drawing or equipment manufacturer documentation - do not substitute generic torque values. Zinc-plated fasteners are not rated for highly corrosive or submerged environments without additional protective measures.
