Value Collection 8836CH8O Hex Cap Screw 7/8-14 Grade 8

Product Description

The VALUE COLLECTION 8836CH8O is a partially threaded hex head cap screw designed for high-strength bolted connections in industrial, mechanical, and structural applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers a tensile strength of 150,000 psi and corrosion resistance suitable for demanding service environments. The 7/8-14 UNF thread size and 2-1/4-inch length under head make it a standard choice for precision-fit assemblies where fine-thread engagement and controlled clamping force are required. Installation is performed with a 1-5/16-inch hex wrench or socket. It conforms to ASME B18.2.1 and SAE J429 standards.

This cap screw is suited for use in heavy equipment, industrial machinery, agricultural implements, hydraulic assemblies, and structural steel connections where Grade 8 strength ratings are specified. The fine UNF thread pattern provides superior thread engagement and vibration resistance compared to coarse-thread equivalents, making it appropriate for applications subject to dynamic or cyclic loading. Machinists, millwrights, equipment technicians, and maintenance professionals routinely use this fastener class in both OEM manufacturing and field repair contexts.

Key Features

• Grade 8 steel construction with 150,000 psi minimum tensile strength
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• 7/8-14 UNF fine thread for precise torque control and vibration resistance
• Partially threaded shank for shear-load bearing and precise hole alignment
• Meets ASME B18.2.1 and SAE J429 standards for dimensional and mechanical compliance
• 1-5/16-inch hex drive compatible with standard hex sockets and wrenches

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 7/8-14 UNF partially threaded hex head cap screw meeting Grade 8 mechanical and ASME B18.2.1 dimensional requirements.

Installation Notes

Installation should be performed by qualified technicians familiar with torque specifications for Grade 8 fasteners in the relevant application. Always de-energize, depressurize, or otherwise make safe the assembly before replacing structural fasteners. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer or applicable engineering standard. Inspect threads for damage and ensure mating surfaces are clean and free of debris before installation.
