Value Collection 014151PS Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 014151PS is a hex socket cap screw designed for secure mechanical fastening in applications requiring corrosion resistance and high tensile strength. Featuring a 5/8-11 UNC thread size and a 2.5-inch length under head, this fastener accepts a 0.5-inch hex drive for tightening with a standard Allen or hex key. Constructed from 316 stainless steel with a bright uncoated finish, it is well suited for environments exposed to moisture, chemicals, or salt where carbon steel fasteners would corrode. Machinists, millwrights, pipefitters, and maintenance technicians commonly specify this grade and thread combination for structural and equipment assembly work.

This screw is used across a wide range of commercial and industrial applications including pump assemblies, pipe flanges, marine hardware, food processing equipment, and HVAC structural components. The 5/8-11 UNC thread form is a coarse-thread standard, making it practical for general fastening where vibration resistance and ease of assembly in field conditions are priorities. The 316 stainless grade offers superior chloride resistance compared to 304, making it a common choice in coastal, chemical, and wet-service environments.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes
• 2.5-inch length under head for adequate thread engagement in thick assemblies
• 316 stainless steel construction for elevated corrosion resistance in harsh environments
• Bright uncoated finish maintains dimensional accuracy and does not add coating thickness to thread fit
• 0.5-inch hex socket drive for use with standard Allen keys or hex bit sockets

Compatibility

Designed as an OEM-style replacement or direct-use fastener for any application specifying a 5/8-11 UNC hex socket cap screw with a 2.5-inch length under head in 316 stainless steel.

Installation Notes

Installation requires a 0.5-inch hex key or hex bit socket rated for the required torque. Always verify that the mating tapped hole is clean, free of debris, and cut to the correct UNC thread specification before installation. Apply anti-seize compound when installing stainless steel fasteners into stainless steel threads to prevent galling. Torque to the value specified by the equipment manufacturer or applicable structural code for the joint being assembled.
