Value Collection -30165-9 Hex Cap Screw 7/8-9 X 9 in Grade 5

Product Description

The VALUE COLLECTION -30165-9 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 7/8-9 UNC thread with a 9-inch length under the head, manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. The hex drive head allows installation with standard wrenches or impact drivers. Conforming to ASME B18.2.1, this fastener meets established dimensional and strength standards for inch-series hex cap screws. It is suited for medium-strength fastening tasks across a range of industrial, mechanical, and maintenance applications.

This fastener is appropriate for use in general manufacturing, equipment assembly, maintenance and repair operations, and structural fastening where a Grade 5 rated, partially threaded hex cap screw in a 7/8-9 UNC thread form is specified. The zinc-plated coating provides a baseline level of corrosion resistance suitable for indoor and light-duty outdoor environments. It is typically installed by millwrights, maintenance technicians, pipefitters, and general tradespeople working on mechanical assemblies and equipment frames.

Key Features

• 7/8-9 UNC thread size with 9-inch length under head
• Partially threaded shank for applications requiring an unthreaded grip length
• Grade 5 steel construction for medium-strength fastening requirements
• Zinc-plated finish provides basic corrosion resistance
• Conforms to ASME B18.2.1 dimensional standard for inch-series hex cap screws

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 7/8-9 UNC partially threaded fastener conforming to ASME B18.2.1.

Installation Notes

Install using a properly sized open-end, box, or socket wrench rated for the fastener torque requirements of the application. Always consult the equipment manufacturer or applicable engineering specifications for correct torque values before tightening. Inspect mating threads and contact surfaces for damage or contamination prior to installation. Follow applicable codes and safety procedures when working on pressurized, high-load, or safety-critical assemblies.
