Value Collection 97161 Hex Head Cap Screw 5/8-11 X 6 in Grade 5

Product Description

The VALUE COLLECTION 97161 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assembly work. It features a 5/8-11 thread size in the Unified National Coarse (UNC) standard, a 6-inch length under head, and is manufactured from Grade 5 steel without any finish coating. The uncoated surface is suitable for applications where a coating is applied post-installation or where bare steel is acceptable. This fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice for engineers, machinists, millwrights, and maintenance professionals who require consistent tolerances and material grade verification.

This cap screw is suited for general industrial and commercial fastening where a high-strength, partially threaded hex head fastener is required. Typical applications include machine frame assembly, equipment mounting, structural steel connections, and heavy-duty mechanical assemblies. The partial threading allows for a smooth shank section that provides shear strength in bolted joint applications where the grip length matters. It is sold in package quantities of 25 per order.

Key Features

• 5/8-11 UNC thread size provides a coarse, high-engagement thread for strong clamping force
• 6-inch length under head accommodates thick material stacks and long-grip fastening requirements
• Grade 5 steel construction meets minimum tensile strength requirements for medium-to-high load applications
• Partially threaded shank delivers shear resistance along the unthreaded grip zone
• Uncoated finish allows for field-applied coatings, platings, or use in dry indoor environments
• Conforms to ASME B18.2.1 for standardized head dimensions and tolerances

Compatibility

Designed as a standard inch-series hex head cap screw for use with 5/8-11 UNC nuts and tapped holes conforming to Unified National Coarse thread standards in industrial and mechanical assembly applications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using standard hex wrenches, box-end wrenches, or impact tools rated for the fastener grade. Always ensure mating threads are clean, undamaged, and match the UNC 5/8-11 specification before installation. De-energize and lock out equipment before replacing or tightening fasteners in powered machinery. Apply thread lubricant or anti-seize only when specified by the equipment manufacturer or applicable engineering standards.
