Value Collection 42919 Set Screw M5x0.80x6mm Cup Point 50pk

Product Description

The VALUE COLLECTION 42919 is an M5 x 0.80 x 6 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H), the highest strength class for metric set screws. Conforming to DIN 916, it features a hex socket drive sized at 2.50 mm and a cup point geometry that bites into shaft surfaces to resist rotation and axial movement. Overall length is measured at 6 mm. This fastener is used across mechanical assemblies wherever a headless, flush-seating screw is required to lock a shaft, collar, or component in position without protruding above the mating surface.

Cup point set screws in this size range are common in precision mechanical assemblies, motion control components, shaft collars, pulleys, gears, and similar hardware found in HVAC equipment, pump assemblies, and general industrial machinery. The M5 x 0.80 metric thread standard makes this screw compatible with ISO-metric tapped holes. This listing includes a package quantity of 50 pieces, suitable for service stock or production use. Installation requires a 2.50 mm hex key.

Key Features

• Grade 14.9 (45H) alloy steel construction provides high clamp load and resistance to loosening under vibration
• Cup point geometry creates a circular indent on the shaft surface for strong rotational and axial hold
• DIN 916 standard ensures dimensional conformance for metric applications
• Hex socket drive (2.50 mm) allows installation in confined spaces where a headed fastener will not fit
• Headless design seats fully flush or below the mating surface
• Pack of 50 pieces supports service inventory and repeat installations

Compatibility

Designed for use in any ISO-metric M5 x 0.80 tapped hole requiring a DIN 916 compliant cup point set screw.

Installation Notes

A 2.50 mm hex key is required for installation. Ensure the receiving tapped hole is clean and free of debris before threading. Apply consistent torque to seat the cup point firmly against the shaft without stripping the hex socket. De-energize or lock out any rotating equipment before servicing fasteners on shafts or collars.
