Value Collection C52000741 Set Screw M8 X 1.25 Grade 316

Product Description

The VALUE COLLECTION C52000741 is a cup point set screw designed for secure, headless fastening in mechanical assemblies where the fastener must sit flush or below the surface of the workpiece. Threaded M8 x 1.25 with an overall length of 20 mm, it is driven by a 4 mm hex key and conforms to DIN 916 standards. Constructed from Grade 316 stainless steel with Austenitic Grade A4 classification, it delivers strong corrosion resistance suitable for wet, marine, and chemical-exposure environments. Machinists, millwrights, and maintenance technicians install these screws to lock shafts, collars, pulleys, and similar components in position without a protruding head.

This set screw is suited for light industrial, marine, food processing, and general mechanical applications where corrosion resistance is a priority. The cup point geometry bites into the mating surface to resist axial and rotational movement, making it a reliable choice for shaft-collar connections, set positions on linear rails, and fixture work. It is sold in packages of 5, making it practical for both single-task repairs and small-batch production runs.

Key Features

• Cup point tip bites into mating surface for strong axial and rotational holding power
• Grade 316 Austenitic Grade A4 stainless steel for superior corrosion resistance in marine and chemical environments
• Metric M8 x 1.25 thread for compatibility with standard metric tapped holes
• DIN 916 standard construction for consistent dimensional accuracy
• 4 mm internal hex drive for precise torque application with a standard hex key
• Sold in packages of 5 to suit repair and light production needs

Compatibility

Designed as a standard metric replacement or service fastener for applications requiring a DIN 916 cup point set screw in M8 x 1.25 thread size.

Installation Notes

Installation requires a 4 mm hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Power down or de-energize any rotating equipment before installing or adjusting set screws on shafts or collars. Verify that the mating tapped hole is clean and free of debris to achieve full thread engagement across the 20 mm length. Follow applicable machinery safety standards and the equipment manufacturer's fastener specifications when selecting torque levels.
