Value Collection 39168 Hex Head Cap Screw 5/8-11 X 10 in Grade 8

Product Description

The VALUE COLLECTION 39168 is a partially threaded hex head cap screw sized 5/8-11 x 10 inches, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is a high-strength fastener classification suited for heavy-duty bolted connections that require reliable clamp load under vibration or dynamic loading. The zinc yellow dichromate coating provides corrosion resistance in moderately harsh environments. Thread size follows the UNC standard at 5/8-11, and the fastener conforms to ASME B18.2.1 dimensional requirements. This screw is installed by electricians, HVAC technicians, pipefitters, millwrights, and other trade professionals working with structural or mechanical assemblies.

This fastener is used in a wide range of industrial, mechanical, and trade applications where a high-strength UNC hex head cap screw is required. The partial threading is appropriate for through-bolt applications where the unthreaded shank is needed to bear shear loads or to clamp across the full joint thickness without thread engagement in the grip area. It is commonly used in equipment mounting, structural steel connections, machinery assembly, and heavy mechanical installations across residential, commercial, and light industrial settings. Sold in a package quantity of 5.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• Zinc yellow dichromate finish for corrosion resistance in moderate-exposure environments
• Partially threaded shank suits through-bolt and shear-bearing joint applications
• 5/8-11 UNC thread form for broad nut and tapped-hole compatibility
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment
• Packaged in quantities of 5 to suit low-volume service and repair needs

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw conforming to ASME B18.2.1, compatible with any application requiring a Grade 8 partially threaded fastener of this thread size and length.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque requirements for Grade 8 hardware and the joint material being clamped. Use the appropriate hex socket or open-end wrench sized for a 5/8-inch hex head cap screw. Ensure mating nuts or tapped holes are clean and free of debris before assembly. Always verify that the fastener grade and length are appropriate for the load and joint design specified in the applicable engineering or code documentation.
