Value Collection 199546 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 199546 is a partially threaded hex socket cap screw designed for secure, high-torque fastening in mechanical, structural, and industrial assemblies. It features a 1/4-20 UNC thread size with a 1-3/4 inch length under head and accepts a 3/16 inch hex drive. Constructed from 18-8 stainless steel, this fastener offers solid corrosion resistance in wet, outdoor, and chemically exposed environments. The partially threaded shank provides a clamping zone for applications where full threading would compromise joint integrity. Licensed tradespeople and maintenance professionals reach for this fastener when a reliable, reusable connection is required in demanding service conditions.

This screw is suited for use in HVAC equipment panels, plumbing fixture mounting, electrical enclosure assembly, pool equipment housings, and general mechanical fabrication. The 1/4-20 UNC coarse thread pattern engages quickly and resists cross-threading in field conditions. The 3/16 inch hex socket drive allows use with a standard Allen key or hex bit driver, making it practical in tight or confined spaces. It is appropriate for both light commercial and residential trade applications where stainless steel fasteners are specified for corrosion resistance.

Key Features

• 1/4-20 UNC coarse thread for fast, reliable engagement
• 1-3/4 inch length under head for moderate clamping depth
• Partially threaded shank to maximize clamping force across joint interfaces
• 3/16 inch hex socket drive compatible with standard Allen keys and hex bit drivers
• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments

Compatibility

Designed as a general-purpose 1/4-20 UNC hex socket cap screw suitable for mechanical assemblies, equipment panels, and structural fastening applications where 18-8 stainless steel and a partially threaded shank are required.

Installation Notes

Installation is typically performed by mechanical contractors, maintenance technicians, or equipment assemblers using a 3/16 inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before driving. Do not overtighten stainless steel fasteners, as galling can occur without proper lubrication or anti-seize compound. Always de-energize and isolate any equipment before accessing fastened panels or enclosures.
