Value Collection 198619 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 198619 is a fully threaded hex socket cap screw designed for secure fastening in applications where a low-profile, high-strength connection is required. It features a 1/4-20 UNC thread size and measures 0.5 inches in length under the head. The drive type is hex, accepting a 3/16-inch hex key. Constructed from 18-8 stainless steel, this fastener offers reliable corrosion resistance in moisture-prone environments. It is suitable for use by machinists, maintenance technicians, plumbers, and general tradespeople working with metal assemblies, equipment panels, and structural components.

This screw is well suited for light industrial, commercial, and residential trade applications where a recessed drive fastener is preferred for flush or countersunk installations. The 1/4-20 UNC coarse thread is one of the most common unified thread standards, making this fastener a practical stocking item for service vehicles, shop benches, and maintenance kits. Its stainless steel construction makes it appropriate for wet or corrosive environments such as HVAC equipment rooms, plumbing chases, and pool equipment installations.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank provides maximum thread engagement along the entire 0.5-inch length under head
• 3/16-inch hex socket drive for use with a standard Allen key or hex bit driver
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Low-profile socket cap head allows installation in recessed or space-constrained locations

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any tapped hole or threaded insert meeting the UNC 1/4-20 thread specification.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver. Always ensure the mating tapped hole is clean and free of debris before threading the fastener. Power down or de-energize any equipment before performing fastener service on electrical enclosures or mechanical assemblies. Do not overtighten stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound.
