Value Collection 837159PR Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 837159PR is a hex socket cap screw designed for fastening applications requiring a recessed hex drive and a secure, torque-resistant hold. Sized at 1/4-20 UNC threading with a 1-3/4 inch length under head, this screw is partially threaded and driven by a 3/16 inch hex key. Constructed from alloy steel with a zinc-plated finish, it offers corrosion resistance suitable for general industrial and mechanical assembly environments. This fastener meets ASTM B695 standards and is suited for use by millwrights, maintenance technicians, and mechanical contractors working on equipment assembly or structural component fastening.

This screw is commonly used in light to medium industrial applications including machinery assembly, equipment mounting, and structural fastening where a flush or low-profile cap head is required. The partial threading allows for clamping force between joined materials without threading through the entire grip length, making it appropriate for joining components of defined thickness in fabrication and maintenance scenarios.

Key Features

• 1/4-20 UNC thread size for compatibility with standard unified coarse thread fastener systems
• 1-3/4 inch length under head provides adequate grip length for multi-layer assemblies
• Partially threaded shank for improved clamping performance between mated surfaces
• 3/16 inch hex socket drive for use with standard hex keys and Allen wrenches
• Alloy steel construction for strength in demanding mechanical environments
• Zinc-plated finish meeting ASTM B695 for corrosion resistance in general-use applications

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application requiring a partially threaded alloy steel fastener with a 3/16 inch hex drive.

Installation Notes

Installation requires a 3/16 inch hex key or Allen driver; use of a calibrated torque wrench is recommended to avoid stripping the socket or over-stressing the fastener. Ensure mating threads are clean and free of debris before driving. Follow applicable mechanical or equipment manufacturer specifications for torque requirements on 1/4-20 fasteners in the target assembly. Minimum order quantity for this SKU is 100 pieces.
