Value Collection 872169PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 872169PR is a hex socket cap screw designed for threaded fastening applications requiring a compact, recessed-drive head. Sized at 1/4-20 UNC with a 3-inch length under the head, this screw features a 3/16-inch hex socket drive and is partially threaded along its shank. It is manufactured from alloy steel with a zinc-plated finish that provides a baseline level of corrosion resistance. Fasteners in this category are installed by maintenance technicians, millwrights, pipefitters, and general contractors working on mechanical assemblies, equipment mounting, and structural fixtures.

This screw is suited for mechanical and industrial applications where a flush or low-profile fastener head is required. The 1/4-20 UNC thread pattern is a standard coarse-thread designation used in a wide range of equipment and structural assemblies across commercial and industrial settings. The partial threading of the shank makes it appropriate for applications requiring a shoulder-like grip through a clearance hole before engaging a tapped bore.

Key Features

• 1/4-20 UNC coarse-thread pattern for broad compatibility with standard tapped hardware
• 3 inches length under head for fastening through thicker materials or stacked components
• 3/16-inch hex socket drive accepts standard Allen or hex key tools
• Partially threaded shank provides a smooth grip section for clearance-hole applications
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 standards
• Zinc-plated finish offers basic corrosion protection in dry or low-moisture environments

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574, suitable for use in any application requiring a fastener to that specification.

Installation Notes

Install using a 3/16-inch hex key or Allen driver; ensure the mating tapped hole conforms to 1/4-20 UNC thread standards before driving. De-energize and lock out any equipment before replacing or tightening fasteners on powered assemblies. Do not exceed the rated torque range for the fastener grade, and inspect zinc-plated finishes for coating damage before use in corrosive environments.
