Value Collection 011289PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011289PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural components. Manufactured from alloy steel with a black oxide finish, this fastener measures 7/8 inches in length under the head and carries a 3/8-24 UNF thread size. The 5/16-inch hex drive accepts a standard hex key or Allen wrench for installation and removal. It is fully threaded along its usable length, making it well suited for clamping into tapped holes without a separate nut. Machinists, millwrights, maintenance technicians, and fabricators are the primary installers of this fastener type.

This screw is appropriate for use in precision machinery, fixtures, equipment housings, and general industrial assemblies where a flush or recessed fastener head is required. The 3/8-24 UNF fine thread pitch provides greater thread engagement per inch compared to coarse thread variants, which supports higher clamping loads and finer torque control. The black oxide coating offers mild corrosion resistance and reduces surface reflectivity in finished assemblies. This fastener is sold individually but carries a minimum order quantity of 100 units, making it suitable for shop stock and production line use.

Key Features

• 3/8-24 UNF fine thread for precise clamping and higher thread engagement
• Fully threaded body for direct installation into tapped holes
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• 5/16-inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any assembly requiring a 3/8-24 UNF hex socket cap screw with a 7/8-inch length under head and a 5/16-inch hex drive.

Installation Notes

Installation is performed with a 5/16-inch hex key or T-handle Allen wrench inserted fully into the drive socket to prevent cam-out and fastener damage. Always verify the mating tapped hole thread specification matches 3/8-24 UNF before installation. De-energize and lock out all equipment before accessing any fastener location on live machinery. Follow applicable torque specifications from the equipment manufacturer or a recognized fastener torque reference for alloy steel socket cap screws at this diameter and thread pitch.
