Value Collection 198624 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 198624 is a fully threaded hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, equipment repairs, and structural applications. Sized at 1/4-20 UNC with a 1-inch length under head, this screw accepts a 3/16-inch hex drive and is manufactured from 18-8 stainless steel for corrosion resistance in demanding environments. The 18-8 alloy grade provides a practical balance of strength and resistance to rust, making it suitable for both indoor and outdoor service work. Trade pros in HVAC, plumbing, electrical, and general equipment maintenance will recognize this as a standard fastener for panel, bracket, and component mounting.

This cap screw is used across a wide range of residential and commercial applications wherever a recessed hex drive fastener is required. Typical install scenarios include securing access panels, mounting brackets, equipment frames, and control board housings. The 1/4-20 UNC thread form is one of the most common coarse-thread standards in North American trade applications, making this screw a frequent go-to for field repairs and equipment assembly. Fully threaded along the shank, it provides maximum thread engagement across the full fastened length.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 1-inch length under head with full threading along the entire shank
• 3/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Cap screw head style provides a low-profile, flush-seating fastener for tight clearance applications

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for any application requiring a 1/4-20 coarse-thread fastener with a 3/16-inch hex drive.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen-head driver bit. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading or galling, which is a particular risk with stainless steel fasteners. Apply an appropriate anti-seize compound when fastening stainless into stainless threads to prevent galling. Power down or de-energize any equipment before accessing internal mounting fasteners.
