Value Collection C52000739 Set Screw M8x1.25x10mm Grade 316

Product Description

The VALUE COLLECTION C52000739 is a metric cup point set screw designed for secure, flush fastening in mechanical assemblies. Manufactured from Grade 316 stainless steel to the Austenitic Grade A4 specification, this screw provides strong corrosion resistance in wet, chemical, and marine environments. It carries an M8 x 1.25 thread and measures 10 mm in overall length. Drive engagement is via a 4 mm hex key socket, conforming to DIN 916. Machinists, millwrights, and maintenance technicians use cup point set screws to lock shafts, collars, gears, and pulleys in position without a protruding fastener head.

This set screw is suited for use in light to medium-duty shaft retention applications across industrial, marine, food processing, and HVAC equipment environments where standard carbon steel fasteners would corrode. The cup point geometry bites into the mating surface to resist rotational and axial movement under load. Sold in a package quantity of 5 with a minimum order quantity of 1 package, this SKU is well suited for service technicians, machine shops, and MRO stockrooms that need a small quantity of metric stainless fasteners on hand.

Key Features

• M8 x 1.25 metric thread, 10 mm overall length for compact flush-mount installation
• Grade 316 Austenitic A4 stainless steel for superior corrosion and chloride resistance
• Cup point geometry provides positive shaft or workpiece bite to resist rotation and axial shift
• 4 mm hex key drive conforms to DIN 916 dimensional standard
• Headless design sits flush or below surface, eliminating snagging hazards in rotating assemblies
• Packaged in quantities of 5 per pack with no minimum order beyond one pack

Compatibility

Designed as a DIN 916 metric cup point set screw suitable for M8 x 1.25 threaded bores in shaft collars, shaft couplings, gears, pulleys, and similar mechanical components requiring a headless fastener.

Installation Notes

Installation requires a calibrated 4 mm hex key or hex bit driver. Ensure the mating threaded bore is clean and free of debris before threading. For Grade 316 stainless fasteners, apply an anti-galling compound or thread lubricant to reduce the risk of galling and seizing during torquing. Confirm the assembly is depowered and de-energized before servicing any rotating machinery or shaft components.
