Value Collection 533118P M8x1.25 Cup Point Set Screw 35mm

Product Description

The VALUE COLLECTION 533118P is an M8x1.25 metric coarse thread cup point set screw designed for mechanical fastening applications where a secure, recessed hold is required. With an overall length of 35mm and a 4mm hex key drive, this set screw is manufactured from Grade 14.9 (45H) alloy steel, providing high tensile strength and resistance to shear forces. It is commonly installed by machinists, millwrights, and maintenance technicians to lock rotating components such as collars, pulleys, and gears onto shafts without protruding hardware.

This set screw is suited for industrial and mechanical assembly applications where metric fasteners are specified. The cup point geometry bites into the mating surface to resist axial and rotational movement under load, making it appropriate for moderate-to-heavy-duty shaft retention. Typical installation environments include machine tools, conveyors, drive assemblies, and general industrial equipment requiring M8 coarse-thread fasteners.

Key Features

• M8x1.25 metric coarse thread for compatibility with standard metric tapped holes
• Cup point geometry bites into shaft surface for positive rotational and axial retention
• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• 35mm overall length suits deeper engagement applications
• 4mm internal hex drive for use with standard hex keys or Allen wrenches
• Headless design sits fully below or flush with surrounding surface

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring M8x1.25 metric coarse thread cup point set screws.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 4mm hex key. Before installation, ensure the shaft and tapped hole are clean and free of debris. Apply appropriate thread-locking compound if vibration loosening is a concern. Always torque to the assembly specification provided by the equipment manufacturer.
