Value Collection 198627 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 198627 is a fully threaded hex socket cap screw designed for fastening applications that demand corrosion resistance and reliable clamping force. It features a 1/4-20 UNC thread size and measures 1-1/4 inches in length under the head. The 3/16-inch hex drive accepts a standard hex key or Allen wrench for installation and removal. Constructed from 18-8 stainless steel, this screw resists rust and oxidation in wet, outdoor, and mildly corrosive environments. Machinists, millwrights, HVAC technicians, and maintenance trades use this fastener in equipment assemblies, brackets, and panel mounting where full thread engagement is required.

This screw is suited for light-to-medium duty fastening in residential and commercial mechanical systems, equipment enclosures, and structural brackets. Its 1/4-20 UNC thread is one of the most widely used coarse-thread profiles in North American mechanical trade work. The fully threaded shank allows maximum thread engagement when threading into shallow bosses, thin plates, or threaded inserts. It is commonly used in HVAC equipment cabinets, plumbing fixture brackets, electrical enclosures, and general fabrication where stainless steel is specified for environmental resistance.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and hardware
• Fully threaded shank maximizes engagement in thin or shallow threaded applications
• 18-8 stainless steel construction resists corrosion in wet and outdoor service conditions
• 3/16-inch hex drive accepts standard hex keys for controlled torque installation
• 1-1/4-inch length under head suits medium-depth fastening without bottoming out

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application that accepts this thread profile and drive type. Verify thread depth and clearance before installation.

Installation Notes

A licensed mechanic, millwright, or qualified trade technician should verify thread engagement and torque requirements for the specific assembly before installation. Use a correctly sized 3/16-inch hex key or T-handle driver to avoid rounding the drive socket. Ensure mating threads are clean and free of debris prior to fastening. Avoid mixing stainless steel fasteners with dissimilar metals in applications where galvanic corrosion could compromise the joint over time.
