Value Collection 10152CH8O Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 10152CH8O is a partially threaded hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. It measures 1-14 thread size with a 3-1/4 inch length under head, making it suitable for high-strength fastening applications. Grade 8 steel delivers a tensile strength of 150,000 psi, placing this fastener in the upper tier of inch-series steel bolts. The zinc yellow dichromate coating provides corrosion resistance and serves as a visual indicator of Grade 8 classification. This screw is driven with a 1-1/2 inch hex key and conforms to ASME B18.2.1 and SAE J429 standards. It is appropriate for use by industrial maintenance technicians, millwrights, and mechanical contractors.

This fastener is used in heavy industrial, agricultural, and mechanical assembly applications where high clamping loads are required. The partial thread configuration is preferred when the fastener must pass through a clearance hole or when thread engagement needs to be limited to a specific grip length. Common install scenarios include machinery frames, structural brackets, flanged connections, and equipment mounting. The UNF thread standard suits precision applications where fine thread pitch improves holding strength and resistance to vibration loosening.

Key Features

• Partially threaded shank allows use in clearance-hole and grip-length-controlled assemblies
• UNF thread standard suits vibration-resistant and precision mechanical assemblies
• Conforms to ASME B18.2.1 and SAE J429 dimensional and performance standards
• 1-1/2 inch hex drive size compatible with standard industrial hex tooling

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for inch-series UNF 1-14 threaded applications requiring Grade 8 performance per SAE J429 and ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with high-strength fastener torque requirements. Always degrease or clean mating threads before installation to obtain accurate torque readings. Use a calibrated torque wrench and consult the applicable equipment service manual for the specified torque value, as this information was not provided with this product listing. Do not mix Grade 8 fasteners with lower-grade nuts or hardware, as this can compromise joint integrity.
