Value Collection BT-51624-500-AS Set Screw 5/16-24 X 1/2 in

Product Description

The VALUE COLLECTION BT-51624-500-AS is a Grade 8 alloy steel set screw with a soft brass tip, designed for secure, non-marring clamping applications in mechanical assemblies. The 5/16-24 thread (UNF) and 1/2-inch threaded length allow precise depth adjustment when driven with a hex key. The brass tip makes contact with the mating surface, protecting shafts, rods, or other components from damage during tightening. Machinists, maintenance technicians, and industrial mechanics install these fasteners in shafts, collars, pulleys, gears, and similar assemblies where holding force is required without scarring the workpiece.

This set screw is suited for use in mechanical power transmission components, machine tools, and industrial equipment where a soft-tip point is specified to protect hardened or finished shaft surfaces. The 5/16-24 UNF thread pitch is common in precision assemblies requiring fine thread engagement. It is installed in applications ranging from light manufacturing equipment to HVAC blower wheel shaft collars and motor-driven components where shaft retention is needed without surface damage.

Key Features

• Soft brass tip prevents marring or galling of shafts and mating surfaces during installation
• Grade 8 alloy steel body provides high tensile and torsional strength for secure holding force
• 5/16-24 UNF thread standard supports fine-pitch engagement for precise depth control
• Hex drive socket compatible with standard hex keys and Allen wrenches
• 1/2-inch full threaded length suits shallow to mid-depth boss applications

Compatibility

Designed as a standard 5/16-24 UNF soft-tip set screw for use in any mechanical assembly or component that calls for a Grade 8 alloy steel set screw with a brass tip and hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a properly sized hex key or Allen wrench. Ensure the mating threaded bore is clean and free of debris before driving the screw. Do not exceed the rated tightening torque for the thread size, and confirm shaft alignment before final seating. Always follow applicable machine safety lockout and tagout procedures before servicing rotating equipment.
