Value Collection 03550167 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION 03550167 is a partially threaded hex head cap screw designed for structural and mechanical fastening applications across a wide range of trade and industrial work. Sized at 7/8-9 (7/8 inch diameter, 9 threads per inch, UNC thread standard) with a 3-3/4 inch length under head, this fastener is manufactured from Grade 5 steel and finished with a hot dipped galvanized coating for corrosion resistance. The partial threading allows for a stronger clamping grip between joined materials. Weighing 0.8 pounds, it suits heavy-duty connections where a standard hex drive and reliable holding strength are required.

This cap screw is suited for general construction, mechanical assemblies, structural steel work, HVAC equipment mounting, and heavy equipment fabrication. The hot dipped galvanized finish makes it appropriate for outdoor, wet, or corrosive environments where bare steel fasteners would be prone to rust. Plumbers, HVAC mechanics, electricians, and general contractors commonly use fasteners of this type when securing equipment frames, mounting brackets, flanges, and structural connections that require a coarse UNC thread profile and high clamp load.

Key Features

• 7/8-9 UNC coarse thread profile for strong thread engagement in steel and iron
• 3-3/4 inch length under head suits thicker material stacks and structural joints
• Partial threading provides improved clamping force and shank bearing area
• Grade 5 steel construction meets medium-high strength fastener requirements
• Hot dipped galvanized finish provides corrosion resistance for outdoor and wet installations

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any application calling for a 7/8-9 partially threaded fastener in Grade 5 steel with a hot dipped galvanized finish.

Installation Notes

Installation of this fastener typically requires a standard hex wrench or socket set sized for a 7/8 inch hex head. Always ensure mating threads are clean and free of debris before assembly. Power down or de-energize any equipment before fastening or removing hardware on electrical or HVAC systems. Torque to the specification provided by the equipment manufacturer or applicable structural code for Grade 5 fasteners of this diameter.
