Value Collection R57001034 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION R57001034 is a 1/4-20 UNC hex socket cap screw designed for secure mechanical fastening in assemblies that require a flush or recessed drive interface. The screw measures 7/16 inches under the head and accepts a 3/16-inch hex (Allen) key for installation and removal. Constructed from 18-8 stainless steel with a bright uncoated finish, it resists corrosion in wet, chemical-exposed, or outdoor environments. This fastener is installed by machinists, millwrights, maintenance technicians, and general tradespeople working on equipment, fixtures, panels, and structural assemblies where a low-profile socket drive is required.

This screw is suited for light- to medium-duty fastening applications in residential and commercial settings. Typical uses include machine guarding, equipment enclosures, brackets, and any assembly where access is limited to a socket key rather than an open-end wrench. The 1/4-20 UNC thread form is a coarse-thread standard widely used across industrial, HVAC, and electrical hardware applications. The stainless steel construction makes it appropriate for environments where carbon steel fasteners would corrode over time.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 7/16-inch length under head for controlled engagement depth
• 3/16-inch hex drive for use with standard Allen keys and hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in wet or chemical environments
• Bright uncoated finish — no plating to chip or flake under torque

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or assembly specifying a 1/4-20 coarse-thread socket head cap fastener with a 7/16-inch grip length.

Installation Notes

Install and remove with a 3/16-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which can occur with stainless steel fasteners when over-torqued or driven dry. Apply an appropriate anti-seize compound if repeated removal is expected. Follow applicable mechanical or equipment manufacturer torque guidelines for 1/4-20 stainless fasteners.
