Value Collection MP30604 Hex Head Cap Screw 1/2-13 Grade 316

Product Description

The VALUE COLLECTION MP30604 is a 1/2-13 UNC hex head cap screw measuring 2-1/2 inches under the head, manufactured from Grade 316 stainless steel. The 3/4-inch hex drive accepts standard hex sockets and wrenches. Grade 316 stainless provides elevated corrosion resistance compared to Grade 304, making it a reliable choice in wet, chemical, or marine environments. This fastener suits maintenance techs, plumbers, HVAC installers, and industrial service pros who need a corrosion-resistant threaded fastener for structural or mechanical assemblies.

This screw is used in applications where moisture, salt spray, or chemical exposure would degrade standard carbon steel or lower-grade stainless fasteners. Common install scenarios include pipe flanges, equipment mounting brackets, pump housings, pool and spa mechanical enclosures, and outdoor HVAC equipment frames. The UNC thread form is the standard coarse-thread inch series, compatible with matching 1/2-13 threaded holes, nuts, and inserts across a wide range of trade equipment.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 1/2-13 UNC coarse thread for broad compatibility with standard inch-series hardware
• 2-1/2 inch length under head suits medium-depth through-bolt and flange applications
• 3/4-inch hex head accepts standard sockets and combination wrenches
• Inch measurement system — direct replacement for standard UNC fasteners in trade assemblies

Compatibility

Designed as an OEM-style replacement or service fastener for any assembly requiring a 1/2-13 UNC hex head cap screw with a 2-1/2 inch length under head in Grade 316 stainless steel.

Installation Notes

Installation is performed by the appropriate trade technician based on the assembly type — HVAC, plumbing, or industrial mechanical. De-energize and lock out equipment before disassembling any fastened mechanical joints. Apply an anti-seize compound rated for stainless fasteners to prevent galling, which is common with stainless steel threaded hardware. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
