Value Collection -30160-31/4 Hex Cap Screw 3/4-10 Grade 5

Product Description

The VALUE COLLECTION -30160-31/4 is a partially threaded hex head cap screw sized 3/4-10 UNC by 3-1/4 inches under the head, manufactured from Grade 5 steel with a zinc-plated finish. Grade 5 steel provides a reliable tensile strength suitable for general structural and mechanical fastening applications. The zinc plating offers corrosion resistance in moderately exposed environments. This fastener meets ASME B18.2.1 dimensional standards, making it a straightforward drop-in for applications that specify that standard. Millwrights, maintenance technicians, and general contractors are the typical installers working with hardware of this specification.

This cap screw is suited for general industrial, commercial, and mechanical assembly applications where an inch-series UNC thread and partial threading are required. Partial threading allows the unthreaded shank to bear shear loads and align mating components. Typical use cases include equipment frames, structural steel connections, machinery bases, and similar bolted assemblies. Sold in a package quantity of 25, making it practical for small-batch maintenance work or moderate-scale assembly jobs.

Key Features

• Grade 5 steel construction meets ASME B18.2.1 dimensional standard
• 3/4-10 UNC thread for compatibility with standard inch-series nuts and tapped holes
• 3-1/4 inch length under head with partial threading to support shear load in the unthreaded shank
• Zinc-plated finish provides moderate corrosion resistance in typical service environments
• Package of 25 fasteners per unit for efficient stocking and small-batch use

Compatibility

Designed for use in standard inch-series bolted assemblies requiring a 3/4-10 UNC partially threaded hex head cap screw conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional familiar with inch-series fastener torque requirements for Grade 5 hardware. Ensure mating threads and seating surfaces are clean and free of debris before assembly. Do not exceed the rated proof load for Grade 5 fasteners; consult applicable engineering references or equipment manufacturer specifications for proper torque values. Use calibrated torque tools where joint integrity is critical.
