Bowmalloy 36108 Hex Head Cap Screw 1/2-13 X 2 in Grade 9

Product Description

The BOWMALLOY 36108 is a Grade 9 alloy steel hex head cap screw sized 1/2-13 x 2 inches, finished with a clear zinc chromate plating for corrosion resistance. This fastener is partially threaded, providing shank strength where thread engagement is not required along the full length of the bolt. Grade 9 alloy steel offers higher proof strength than standard Grade 5 or Grade 8 hardware, making it appropriate for high-stress structural and mechanical assemblies. It is installed by mechanics, pipefitters, millwrights, and general trade professionals working in industrial, commercial, and heavy-duty applications.

The 36108 is suited for bolted connections in structural steel, machinery frames, brackets, and other load-bearing assemblies where a high-strength inch-series fastener is required. The 1/2-13 thread designation follows Unified National Coarse (UNC) standards. The clear zinc chromate finish provides a base level of corrosion protection appropriate for indoor or sheltered installations. Sold in a package quantity of 50 units with a minimum order quantity of 1 package.

Key Features

• Grade 9 alloy steel construction for elevated proof and tensile strength beyond standard Grade 8 fasteners
• 1/2-13 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• 2-inch length under head with partial threading to preserve shank integrity in clearance-hole applications
• Clear zinc chromate finish provides corrosion resistance in dry or sheltered environments
• Hex head drive for use with standard open-end, box, or socket wrenches
• Package quantity of 50 units minimizes downtime for high-volume fastening work

Compatibility

Designed as a high-strength inch-series hex head cap screw for use in any bolted connection requiring a 1/2-13 UNC thread and 2-inch grip length. Verify nut or tapped-hole thread class and proof load requirements before substituting for any existing fastener specification.

Installation Notes

Installation should be performed by qualified mechanical or structural tradespeople following applicable torque specifications for Grade 9 fasteners as defined by the fastener manufacturer or the governing engineering specification for the assembly. Always degrease mating surfaces before assembly unless a specific lubricant or thread compound is called for by the design spec. Do not substitute this fastener in applications requiring a different grade, thread pitch, or finish without engineering review. Fastener torque values are assembly-specific and are not provided here.
