J.w. Winco 913.3-M6-12-MS M6 Set Screw Soft Tip Steel

Product Description

The J.W. WINCO 913.3-M6-12-MS is a metric hex-drive set screw designed for controlled clamping and positioning applications in mechanical assemblies. Threaded M6 x 1.00 with a 12 mm thread length, it is manufactured from Grade 5.8 steel and finished in black oxide for corrosion resistance. The soft brass tip protects shaft surfaces and seated components from damage during tightening, making it a practical choice for precision positioning work. A 3 mm hex key drives the fastener. This part is installed by millwrights, machine builders, maintenance technicians, and mechanical assemblers working with metric hardware.

This set screw is suited for use in shaft collars, shaft couplings, pulleys, sprockets, gears, and similar mechanical components where a non-marring or reduced-mar tip is required. The brass soft tip compresses slightly against the mating surface, reducing the risk of scoring precision ground shafts. It is appropriate for light to medium clamping loads in industrial, automation, and general mechanical assembly environments where RoHS-compliant materials are required.

Key Features

• M6 x 1.00 metric thread, 12 mm thread length
• Grade 5.8 steel construction for reliable clamping strength
• Brass soft tip reduces shaft marring during installation and adjustment
• 3 mm hex key drive for standard tooling compatibility
• Black oxide finish provides mild corrosion resistance
• RoHS compliant materials

Compatibility

Designed as a direct-fit metric set screw for shaft collars, couplings, pulleys, and similar hardware requiring an M6 x 1.00 soft-tip fastener with a 3 mm hex drive.

Installation Notes

Install using a 3 mm hex key; ensure the mating threaded hole is clean and free of debris before engagement. Disengage or de-energize any rotating or powered equipment before servicing fasteners on shafts or drive components. Do not exceed the rated clamping load for Grade 5.8 fasteners, and do not substitute this soft-tip screw in applications requiring a hardened cup-point or cone-point for positive shaft locking under high torque.
