Value Collection 42913 M4 Set Screw Cup Point Alloy Steel 50pk

Product Description

The VALUE COLLECTION 42913 is an M4 x 0.70 x 10 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). Set screws of this type are headless fasteners that thread fully into a tapped hole and bear down on a shaft or mating surface to lock components in position without protruding hardware. The cup point creates a slight indentation in the mating surface for a secure, positive hold. Drive is via a 2.00 mm hex key. This fastener meets DIN 916 dimensional standards and is appropriate for mechanical assemblies, shaft collars, pulleys, and similar industrial or trade applications.

This set screw is suited for general mechanical and industrial maintenance work where an M4 metric thread is required. The overall length of 10 mm and cup point geometry make it appropriate for light-duty shaft-locking applications in equipment found across HVAC, plumbing, electrical, and general industrial environments. Each package contains 50 pieces, providing enough quantity for production runs, bench stock, or service kit replenishment. Installation requires only a 2.00 mm hex key, keeping tooling requirements minimal in the field.

Key Features

• M4 x 0.70 metric thread with 10 mm overall length
• Cup point design indents mating surface for positive shaft retention
• Grade 14.9 (45H) alloy steel construction for high tensile strength
• Hex drive requires a 2.00 mm hex key — no special tooling needed
• Conforms to DIN 916 fastener standard
• Sold in a 50-piece package to support bench stock and production use

Compatibility

Designed as a DIN 916 standard metric set screw compatible with any tapped M4 x 0.70 threaded bore requiring a cup point headless fastener.

Installation Notes

Installation is performed by threading technicians or maintenance mechanics using a 2.00 mm hex key. Ensure the mating bore is clean and properly tapped to M4 x 0.70 before installation. De-energize or lock out any rotating equipment before removing or installing set screws to prevent injury. Do not over-drive the screw beyond flush or specified seating depth, as this may strip threads or damage the mating shaft.
