Value Collection -30604-31/4 Hex Cap Screw 1/2-13 316 Ss

Product Description

The VALUE COLLECTION -30604-31/4 is a partially threaded hex head cap screw sized 1/2-13 x 3-1/4 inches, manufactured from Grade 316 stainless steel with an uncoated finish. This fastener follows Unified National Coarse (UNC) thread standards and is measured under the head. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, making this screw suitable for demanding environments where standard carbon steel fasteners would degrade. Licensed tradespeople and maintenance technicians reach for this fastener when assembling or securing components in corrosive or high-moisture service conditions.

This hex head cap screw is well suited for mechanical, plumbing, HVAC, and industrial assembly applications where corrosion resistance is a priority. The 1/2-13 UNC thread pattern is a widely used coarse-thread specification, compatible with standard hex nuts and tapped holes of the same designation. Partially threaded construction provides a smooth shank section useful for joints requiring a grip length or precise clamping without thread interference in the bearing area.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance
• 1/2-13 UNC thread specification for broad compatibility with standard hardware
• 3-1/4 inch length measured under the head
• Partially threaded shank for controlled clamping and grip-length applications
• Uncoated finish retains the natural corrosion-resistant properties of 316 alloy
• Inch measurement system; standard hex drive for common hand and power tools

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw for use with any matching 1/2-13 UNC nut, washer, or tapped hole conforming to inch-series thread standards.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or maintenance technician familiar with fastener torque requirements for the specific joint material and load rating. Always confirm thread engagement depth and verify that mating hardware matches the 1/2-13 UNC specification before assembly. Use an appropriate hex wrench or socket; do not use adjustable tools that may round the head under high torque. Inspect threads for damage or contamination before installation to ensure full engagement and proper clamping force.
