Value Collection -30174-3 Hex Cap Screw 1-1/4-7 X 3 in Grade 5

Product Description

The VALUE COLLECTION -30174-3 is a fully threaded hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance. The 1-1/4-7 UNC thread profile and 3-inch length under head make it suited for heavy structural and mechanical assemblies where a coarse-thread, large-diameter fastener is required. Installation is straightforward with standard hex tooling. This screw is sold in a package quantity of 10.

This hex head cap screw fits into a broad range of industrial, mechanical, and structural applications requiring Grade 5 UNC fasteners. The fully threaded shank maximizes thread engagement across the full clamping length, making it appropriate for through-bolt configurations. It is commonly used in equipment framing, machinery assembly, and general fabrication work where a zinc-plated steel fastener meets the load and environmental requirements of the application.

Key Features

• Fully threaded shank for maximum thread engagement along the entire 3-inch clamping length
• Grade 5 steel construction for medium-high tensile strength in structural and mechanical applications
• Zinc-plated finish provides basic corrosion resistance in dry to mildly humid environments
• 1-1/4-7 UNC (Unified National Coarse) thread standard for broad tooling and nut compatibility
• Inch measurement system; length measured under the head
• Package quantity of 10 per order unit

Compatibility

Designed as a standard UNC hex head cap screw replacement for industrial, mechanical, and structural assemblies requiring a 1-1/4-7 thread size and 3-inch length under head in Grade 5 steel.

Installation Notes

Installation is performed with a standard hex wrench or socket sized for a 1-1/4-7 hex head fastener. Torque to the appropriate value per the assembly specification and applicable standards for Grade 5 fasteners. Always verify thread engagement depth and mating nut or tapped hole condition before final assembly. Zinc-plated fasteners should not be used in applications requiring galvanic isolation or where the finish is incompatible with the mating material.
