Value Collection 99110 Hex Head Cap Screw 1/2-13 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION 99110 is a Grade 8 steel hex head cap screw with a 1/2-13 UNC thread and a 2-1/2 inch length under head. Partially threaded and left uncoated, it delivers the high tensile strength and shear resistance that structural and mechanical fastening applications demand. Manufactured to ASME B18.2.1 standards, this fastener meets consistent dimensional tolerances expected in professional trade and industrial work. It is appropriate for use wherever a high-strength inch-series hex cap screw is required, and is sold in a package quantity of 25.

This screw is used in heavy equipment assembly, structural steel connections, machinery fabrication, and general industrial maintenance. The 1/2-13 UNC thread is one of the most common inch-series thread sizes encountered in mechanical and structural work. The partially threaded shank provides a bearing surface that resists lateral shear loads in bolted joint applications. Mechanical contractors, millwrights, and maintenance technicians will find this fastener appropriate for a wide range of bolted connection tasks requiring Grade 8 performance.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1/2-13 UNC thread form, partially threaded shank
• 2-1/2 inch length under head per ASME B18.2.1 dimensional standard
• Uncoated finish suitable for use with plated nuts or where coating is not required
• Sold in a package of 25 fasteners

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1/2-13 UNC threaded holes and nuts conforming to ASME B18.2.1 specifications in structural and mechanical assemblies.

Installation Notes

Installation is performed by mechanical contractors, millwrights, or maintenance technicians using standard hex wrenches or impact tools appropriate for 1/2-inch fasteners. Always verify that the mating nut or tapped hole is also rated for Grade 8 or equivalent load requirements before torquing. De-energize, depressurize, or otherwise isolate the assembly before disassembling any bolted joint under load. Follow applicable codes and engineering specifications for torque values, as none are specified for this fastener by the manufacturer data provided.
