Value Collection C52000740 Set Screw M8 X 1.25 Din 916

Product Description

The VALUE COLLECTION C52000740 is an M8 x 1.25 x 16 mm cup point set screw manufactured from Grade 316 austenitic stainless steel (Grade A4) and conforming to DIN 916. Set screws are headless fasteners driven entirely below the surface of a mating part, using internal hex drive to generate clamping force at the cup point. This screw is suited for securing collars, hubs, pulleys, and similar components onto shafts or in threaded bores. The Grade 316 stainless construction provides corrosion resistance in wet, chemical, or marine environments. Installation requires a 4.00 mm hex key. Sold in a package of 5.

This set screw is used in light mechanical assemblies, shaft-collar connections, and precision positioning applications across industrial, marine, food-processing, and general manufacturing environments. The cup point geometry bites into the mating shaft surface to resist axial and rotational movement. The metric thread standard and DIN 916 compliance make this fastener appropriate for equipment designed to metric specifications. It is typically installed by machinists, maintenance technicians, and mechanical assemblers working on metric-standard machinery.

Key Features

• M8 x 1.25 metric thread with 16 mm overall length
• Cup point geometry for positive grip on shaft surfaces
• Grade 316 austenitic stainless steel (Grade A4) for corrosion resistance
• DIN 916 fastener standard compliance
• Internal hex drive accepts a 4.00 mm hex key
• Headless design seats fully below the mating surface

Compatibility

Designed as an OEM-style replacement or service fastener for metric-threaded applications requiring an M8 x 1.25 DIN 916 cup point set screw in stainless steel.

Installation Notes

Install using a calibrated 4.00 mm hex key; do not use worn or undersized keys, as they can round the drive socket. De-energize or lock out any rotating equipment before accessing shaft-collar assemblies per applicable safety procedures. Verify thread engagement depth and torque to the equipment manufacturer's specification. Grade 316 stainless fasteners may be susceptible to galling on stainless mating surfaces; apply an anti-galling compound where appropriate.
