Value Collection 533508PR Set Screw M2 X 0.40 Cup Point

Product Description

The VALUE COLLECTION 533508PR is an M2 x 0.40 x 2.5 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). This fully threaded headless fastener is driven with a 0.90 mm hex key and conforms to DIN 916, the internationally recognized standard for hexagon socket set screws with cup point. The cup point geometry bites into the mating surface to resist rotation and axial movement without a protruding head. At Grade 14.9 (45H), the alloy steel construction delivers high hardness and tensile strength suitable for demanding clamping and locking applications.

This set screw is used in light mechanical assemblies where a flush or recessed fastener is required. Common applications include shaft-to-collar connections, positioning of gears and pulleys on small-diameter shafts, and fixture or tooling assemblies in industrial and maintenance settings. The metric M2 thread size makes it appropriate for precision equipment, instrumentation, and small-component assemblies where space is constrained. These screws are typically installed by machinists, millwrights, and maintenance technicians working with metric hardware.

Key Features

• Cup point geometry bites into the shaft surface for positive grip without a protruding head
• Grade 14.9 (45H) alloy steel provides high hardness and load-bearing capability
• Conforms to DIN 916 standard for consistent dimensional and mechanical tolerances
• Metric M2 x 0.40 thread with 2.5 mm overall length for compact, precision installations
• Driven with a 0.90 mm hex key for access in tight spaces
• Fully threaded, headless design sits flush or below the mating surface

Compatibility

Designed as a standard DIN 916 metric set screw for use in any M2 x 0.40 threaded hole requiring a cup point, headless configuration.

Installation Notes

Install with a 0.90 mm hex key; use a calibrated torque driver where joint integrity is critical and consult applicable assembly specifications for the required seating torque. Ensure the mating threaded hole is clean and free of debris before installation. Do not exceed the torsional limits of the M2 thread, as over-torquing small-diameter screws can cause thread stripping or screw shear. A thread-locking compound may be applied when vibration resistance is required.
