Value Collection C89632 Hex Head Cap Screw 9/16-18x5 Grade 5

Product Description

The VALUE COLLECTION C89632 is a partially threaded hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 5 steel with a zinc yellow dichromate finish, this fastener delivers a reliable combination of tensile strength and corrosion resistance suitable for demanding assemblies. The 9/16-18 thread is a unified fine (UNF) designation, providing finer thread engagement and greater resistance to loosening under vibration compared to coarse-thread equivalents. At 5 inches under the head, it accommodates deeper stack assemblies. This screw conforms to ASME B18.2.1, the standard governing inch hex head bolts and screws. It is sold in packages of 10 units.

This fastener is used in structural, mechanical, and equipment assembly work across manufacturing, maintenance, and repair operations. The partial threading is suited for applications where a smooth shank is required in the grip length, such as bolt joints with close-tolerance clearance holes or shear-loaded connections. Licensed millwrights, machinists, and maintenance mechanics will encounter this fastener in equipment assembly, machine frames, and general MRO applications requiring a fine-thread, medium-strength fastener.

Key Features

• Grade 5 steel construction provides minimum tensile strength of 120,000 psi for medium-strength fastening
• Zinc yellow dichromate finish offers corrosion resistance and serves as a visual grade identifier
• 9/16-18 UNF thread delivers finer pitch for improved vibration resistance versus coarse-thread variants
• Partial threading preserves a smooth shank grip length for shear-loaded and close-tolerance joints
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Sold in a package of 10 units to support single-job or small-batch needs

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 9/16-18 UNF threaded hole or nut meeting ASME B18.2.1 dimensional requirements.

Installation Notes

Installation is typically performed by millwrights, machinists, or qualified maintenance mechanics using an appropriate hex wrench or socket. Always verify that mating threads are clean, undamaged, and of the correct thread class before installation. Apply thread lubricant or anti-seize as required by the joint specification to achieve accurate clamp load from applied torque. Consult the equipment manufacturer torque specification and applicable industry standards for proper tightening procedure.
