Value Collection C704252 Hex Cap Screw 1/2-13 X 10 in Grade 8

Product Description

The VALUE COLLECTION C704252 is a Grade 8 steel hex head cap screw in a 1/2-13 UNC thread size with a 10-inch length under head. Partially threaded, it is engineered for high-strength bolted connections where a full-thread grip is not required or desired. The zinc yellow dichromate finish provides corrosion resistance suitable for general industrial and mechanical assembly environments. Compliance with ASME B18.2.1 and SAE J429 confirms dimensional accuracy and minimum tensile strength standards expected for Grade 8 fasteners. Technicians and tradespeople can rely on consistent head geometry and thread tolerance for repeatable torque-to-yield installations.

This cap screw is used in heavy-duty mechanical assemblies, structural connections, and equipment mounting applications across industrial, construction, and trade service settings. The 1/2-13 coarse thread pattern is one of the most common inch-series fastener sizes, making this screw applicable to a wide range of machinery, structural steel, and equipment frames where Grade 8 strength is specified. The partial thread shank provides a bearing surface useful in shear-load applications or when clamping through clearance holes.

Key Features

• Grade 8 steel construction meets SAE J429 minimum proof load and tensile strength requirements
• 1/2-13 UNC thread pattern — one of the most widely used inch-series coarse thread designations
• 10-inch length under head accommodates thick stacks, structural members, and deep clearance holes
• Partially threaded shank provides a clean bearing surface for shear-load and clamping applications
• Zinc yellow dichromate finish adds corrosion resistance over bare steel
• Conforms to ASME B18.2.1 for head dimensions and SAE J429 for mechanical properties

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 1/2-13 UNC Grade 8 fastener per ASME B18.2.1 and SAE J429.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque specifications for Grade 8 hardware. Always consult the equipment manufacturer or applicable engineering standard for the correct torque value before tightening. Ensure mating threads are clean, free of debris, and in good condition prior to assembly. Use appropriate hand tools or power tools rated for 1/2-inch drive to avoid damaging the hex head or thread form.
