Value Collection 72216 Hex Socket Cap Screw 7/16-14 Unc 25pk

Product Description

The VALUE COLLECTION 72216 is a partially threaded hex socket cap screw engineered for high-strength fastening in mechanical, structural, and industrial assemblies. Sized at 7/16-14 UNC with a 4-inch length under the head, this fastener accepts a 3/8-inch hex drive and is manufactured from alloy steel with a black oxide coating for corrosion resistance. Sold in a pack of 25, it is well suited for production environments, maintenance shops, and field service technicians who need a reliable, standardized fastener on hand. The black oxide finish reduces light reflection and provides moderate surface protection in dry to mildly humid environments.

This screw is appropriate for use in general mechanical assemblies, machine frames, jigs, fixtures, and equipment mounting applications where a recessed drive is preferred for torque control and flush-head clearance. The 7/16-14 UNC thread designation makes it compatible with standard unified coarse-thread tapped holes and nuts of the same specification. It meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards, making it suitable for applications that require documented dimensional compliance.

Key Features

• 7/16-14 UNC thread for compatibility with standard unified coarse-thread applications
• 4-inch length under head provides substantial grip length for thick material stacks
• 3/8-inch hex socket drive for use with standard hex keys and socket drive tools
• Alloy steel construction delivers high tensile and shear strength
• Black oxide coating reduces surface corrosion and minimizes light reflection
• Partially threaded shank allows for precise shoulder clamping in bolted joints
• Meets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 standards

Compatibility

Designed as a standard replacement or stock fastener for any 7/16-14 UNC tapped hole application requiring a hex socket cap screw per ANSI B18.3 dimensional specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and a 3/8-inch hex bit or Allen key. Always de-energize or lock out equipment before fastener service on powered machinery, per applicable OSHA lockout/tagout procedures. Do not reuse fasteners that show thread damage, galling, or coating loss in critical structural joints. Apply thread lubricant or anti-seize only when specified by the assembly drawing, as lubrication affects torque-tension relationships.
