Value Collection D30165-3 Hex Cap Screw 7/8-9 X 3 in Grade 5

Product Description

The VALUE COLLECTION D30165-3 is a 7/8-9 hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It measures 3 inches under the head and features partial threading along the shank. The fastener conforms to ASME B18.2.1 dimensional standards and uses a Unified National Coarse (UNC) thread form. This type of fastener is a standard hardware item installed by electricians, plumbers, HVAC technicians, millwrights, and general contractors wherever structural or mechanical bolted connections are required in trade and industrial applications.

This screw is suited for general mechanical assembly, equipment mounting, structural framing connections, and machinery fastening where a 7/8-9 UNC thread and 3-inch grip length are called for. The partial threading provides a smooth shank section that resists shear loads and allows for precise clamping in bolted joint designs. The zinc-plated finish offers basic corrosion resistance appropriate for indoor and sheltered outdoor applications.

Key Features

• 7/8-9 UNC thread size for high-load bolted connections
• 3-inch length under head with partial threading for shear-load resistance
• Grade 5 steel construction for medium-strength fastener applications
• Zinc-plated finish provides basic corrosion protection
• Conforms to ASME B18.2.1 dimensional standards
• Standard hex head drive for use with common wrenches and sockets

Compatibility

Designed as a standard 7/8-9 UNC hex head cap screw for use in general mechanical and structural bolted assemblies where ASME B18.2.1 compliant fasteners are specified.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 7/8-9 fastener. Always verify thread engagement length and clamping requirements against the application design specifications before installation. Use appropriate washers and nuts as required by the joint design. Follow applicable mechanical codes and equipment manufacturer guidelines for torque and assembly procedures.
