Value Collection MP30603 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION MP30603 is a 1/2-13 x 2 inch hex head cap screw manufactured from Grade 316 stainless steel. The UNC thread pattern runs a 1/2-13 thread size with a 2-inch length under the head, and the hex drive measures 3/4 inches across flats. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making this fastener well suited for wet, chemical, and marine environments. Plumbers, HVAC mechanics, electricians, and general trade contractors reach for 316 stainless hardware when standard carbon steel or 304 grades would corrode in service.

This cap screw is used in trade and industrial applications where moisture, salt, or chemical exposure is a factor. Common installation scenarios include pipe flange connections, equipment mounting in mechanical rooms, pool and water treatment equipment, and outdoor electrical enclosures. The UNC thread form is the standard inch-series coarse thread, compatible with standard hex nuts, T-nuts, and tapped holes dimensioned to 1/2-13 UNC specifications. A minimum order quantity of 25 pieces applies to this SKU.

Key Features

• Grade 316 stainless steel construction for elevated corrosion resistance in wet and chemical environments
• 1/2-13 UNC coarse thread — compatible with standard inch-series hardware
• 2-inch length under head for consistent grip length across typical flange and bracket applications
• 3/4-inch hex drive accepts standard 3/4-inch wrenches and sockets
• Inch system of measurement — dimensioned to ASME/ANSI standards for 1/2-13 fasteners

Compatibility

Designed for use in any application requiring a 1/2-13 UNC hex head cap screw with a 2-inch length under head. Compatible with standard 1/2-13 UNC hex nuts, washers, and tapped holes machined to UNC thread specifications.

Installation Notes

Installation is performed by qualified tradespeople using a 3/4-inch combination wrench, box wrench, or socket. Always ensure mating threads are clean and free of debris before installation. When used in pressurized piping or equipment assemblies, follow applicable code requirements including ASME B31.1 or B31.9 for mechanical systems. Do not mix stainless steel fasteners with dissimilar metals in submerged or high-humidity environments without accounting for galvanic corrosion potential.
