Value Collection 198623 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 198623 is a fully threaded hex socket cap screw designed for fastening applications that demand corrosion resistance and consistent clamping force. Sized at 1/4-20 UNC with a 7/8 inch length under head, this fastener uses a 3/16 inch hex drive and is manufactured from 18-8 stainless steel. The 18-8 grade provides reliable resistance to oxidation and mild chemical exposure, making it a practical choice where carbon steel fasteners would degrade. Machinists, maintenance technicians, and fabricators install these in equipment assemblies, enclosures, and structural fixtures that require a standard unified coarse thread pattern.

This screw fits general industrial and commercial fastening applications. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes used across mechanical assemblies, panel mounting, and equipment fabrication in both light manufacturing and facility maintenance environments. The fully threaded shank maximizes thread engagement throughout the entire length under head, which is preferred when fastening into tapped holes without a shoulder clamp requirement. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• 1/4-20 UNC fully threaded shank for maximum thread engagement in tapped holes
• 18-8 stainless steel construction resists corrosion and oxidation
• 3/16 inch internal hex drive accepts standard hex keys and Allen-style bit drivers
• 7/8 inch length under head suits moderate-depth fastening applications
• Low-profile socket cap head allows installation in recessed or space-constrained areas

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any tapped or through-hole assembly specifying a 1/4-20 unified coarse thread fastener in stainless steel.

Installation Notes

Install using a 3/16 inch hex key or matching driver bit. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading the stainless steel fastener, which is more susceptible to galling than carbon steel. Apply an anti-seize compound when fastening into aluminum or stainless-to-stainless connections to reduce the risk of thread galling. Follow applicable fastener torque specifications from the equipment manufacturer or a standard fastener torque reference chart for 1/4-20 stainless hardware.
