Value Collection 97153 Hex Head Cap Screw 5/8-11 X 3 in Grade 5

Product Description

The VALUE COLLECTION 97153 is a partially threaded hex head cap screw engineered to inch-system dimensional standards. It carries a 5/8-11 UNC thread designation and measures 3 inches under the head. Manufactured from Grade 5 steel in an uncoated finish, it meets ASME B18.2.1 requirements for hex cap screws. This fastener is a standard choice in structural assembly, mechanical fabrication, and equipment maintenance where a recognized strength grade and a clean, uncoated surface are required. Installation is performed with a standard hex wrench or impact driver sized for the 5/8-inch head.

The 97153 is suited for general industrial and mechanical applications requiring a coarse-thread, inch-series cap screw. Partial threading allows the unthreaded shank to bear shear loads through joint interfaces, making it appropriate for bolted connections where shank engagement in the joint is beneficial. It is commonly used in structural steel work, heavy equipment, conveyor systems, and similar trade and fabrication environments where Grade 5 strength is specified.

Key Features

• 5/8-11 UNC coarse thread in inch measurement system
• 3-inch length measured under the head per ASME B18.2.1
• Grade 5 steel construction for medium-high strength applications
• Partially threaded shank for improved shear load performance at joint interfaces
• Uncoated finish — no plating or treatment applied
• Sold in a package quantity of 25 pieces

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw compatible with any 5/8-11 UNC tapped hole or matching hex nut in general mechanical and structural assemblies.

Installation Notes

Installation is typically performed by a machinist, millwright, ironworker, or maintenance technician using a correctly sized hex socket or open-end wrench. De-energize and lock out equipment before fastener replacement in powered machinery per applicable OSHA lockout/tagout procedures. Verify that the mating tapped hole or nut matches the 5/8-11 UNC thread form before installation. Do not over-torque beyond the Grade 5 specification for this thread size as defined in applicable torque reference tables.
