Value Collection 581517PS Hex Socket Cap Screw 7/16-14 Unc

Product Description

The VALUE COLLECTION 581517PS is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assembly, fabrication, and maintenance work. The screw features a 7/16-14 UNC thread size and a 6-inch length under head, making it suitable for through-bolt and deep-clearance installations. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and reduced light reflection in industrial environments. The 3/8-inch hex drive socket accommodates standard Allen keys and hex bit drivers commonly used by machinists, millwrights, and maintenance technicians.

This cap screw is used in general industrial, OEM machinery, and structural fabrication settings where high clamping force and precise torque control are required. The partial threading allows for a smooth shank section that aligns mating components accurately before thread engagement begins. It is well suited for bolting flanges, mounting brackets, machine bases, and other load-bearing assemblies. Licensed trade professionals and shop technicians working in manufacturing, HVAC equipment assembly, or mechanical contracting will find this screw appropriate for standard ASME fastener specifications.

Key Features

• 7/16-14 UNC thread for compatibility with standard inch-series tapped holes
• 6-inch length under head accommodates deep-grip and through-bolt applications
• Partially threaded shank provides alignment before full thread engagement
• Alloy steel construction delivers high tensile and shear strength
• Black oxide coating offers moderate corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any application requiring a 7/16-14 UNC partially threaded hex socket cap screw per ASME/ANSI B18.3 specification.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and a properly sized 3/8-inch hex key or socket bit. Ensure the tapped hole is clean and free of debris before driving the screw. Do not exceed the rated torque for the grade of the mating material. Apply appropriate thread lubricant or thread-locking compound as specified by the equipment manufacturer or applicable code.
