J.w. Winco 913.3-M4-6-MS Set Screw M4 X 0.70 6mm

Product Description

The J.W. WINCO 913.3-M4-6-MS is a metric hex-drive set screw designed for light-duty clamping and positioning applications where a soft-tipped point is required to grip without damaging the mating surface. The screw features an M4 x 0.70 thread, a 6 mm thread length, and a 2 mm hex key drive. The body is Grade 5.8 steel with a black oxide finish, and the brass tip provides the non-marring contact point that makes this fastener suitable for use against shafts, bushings, or precision-machined surfaces. RoHS compliant.

This set screw is used in industrial and mechanical assemblies where a threaded component must be locked or positioned against a shaft or bore without leaving marks or gouging the contact surface. Typical applications include collars, couplings, handles, knobs, and adjustable stops. The soft brass tip absorbs clamping force and protects the mating surface. Licensed electricians, millwrights, mechanical assemblers, and field technicians working with motion-control or machine components will commonly use this fastener type.

Key Features

• M4 x 0.70 metric thread with 6 mm engaged thread length
• Soft brass tip prevents marring or scoring of mating surfaces
• 2 mm hex key drive for precise torque application in tight spaces
• Grade 5.8 steel construction provides reliable clamping strength for light-duty use
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• RoHS compliant for use in environmentally regulated assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for assemblies requiring an M4 x 0.70 metric set screw with a soft tip point and hex drive.

Installation Notes

Install using a 2 mm hex key. De-energize and lock out any equipment before servicing components that use this fastener. Do not over-torque - Grade 5.8 set screws have defined proof load limits, and exceeding them can strip the thread or fracture the fastener. Verify thread engagement and tip contact with the mating surface before returning the assembly to service.
