Value Collection R94184638 Hex Head Cap Screw 1/4-20

Product Description

The Value Collection R94184638 is a 1/4-20 hex head cap screw measuring 3-1/2 inches under the head, manufactured from Grade 316 stainless steel with a bright uncoated finish. The partial threading design follows UNC thread standards, making it appropriate for applications where a grip length under the head is required before threads engage. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, particularly in chloride-rich or marine environments. This fastener suits mechanical assemblies, HVAC brackets, plumbing hardware, and equipment enclosures where corrosion resistance and structural integrity are priorities.

This hex head cap screw is suited for use in residential and commercial trade applications where stainless fasteners are specified. Common installation scenarios include HVAC equipment mounting, pool and spa mechanical enclosures, marine plumbing, and outdoor electrical panel work. The 1/4-20 UNC thread size is a widely used standard in light-gauge equipment frames and bracket assemblies. Partial threading allows the unthreaded shank to bear shear loads in bolted connections, which is a common structural requirement in mechanical trade work.

Key Features

• Grade 316 stainless steel construction for strong resistance to chloride and saltwater corrosion
• Partially threaded shank per UNC standard, suitable for load-bearing bolted connections
• 1/4-20 thread size is widely compatible with standard hex nuts and insert hardware
• Bright uncoated finish maintains dimensional accuracy for close-tolerance applications
• Inch measurement system with length measured under head at 3-1/2 inches

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw compatible with 1/4-20 hex nuts, flat washers, and threaded inserts manufactured to Inch system specifications.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or electricians as part of equipment mounting or panel assembly work. Power down or de-energize any equipment before fastening components to electrical enclosures or mechanical assemblies. Use an appropriate hex wrench or socket driver sized for 1/4-inch hex head cap screws and torque to equipment manufacturer specifications. Avoid mixing Grade 316 stainless fasteners with dissimilar metals in wet environments to prevent galvanic corrosion.
