Value Collection 42925 M5 Set Screw Cup Point Din 916 50-pack

Product Description

The VALUE COLLECTION 42925 is an M5 x 0.80 x 20 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). Set screws are headless fasteners that thread fully into a tapped hole and bear directly against a mating surface or shaft to lock components in place without protruding hardware. The cup point geometry bites into the mating surface for a secure grip under vibration and load. This fastener uses a 2.50 mm hex key drive and conforms to DIN 916, making it a standard metric fastener suitable for precision mechanical assemblies. Sold in a package of 50 pieces per order.

Cup point set screws in M5 x 0.80 x 20 mm are commonly used in light mechanical and industrial applications including shaft collars, pulleys, gears, couplings, and similar rotating or sliding components. This size is well suited for equipment maintenance, machine shops, and production environments where metric DIN-standard fasteners are specified. The Grade 14.9 (45H) alloy steel construction provides high tensile strength for demanding clamping and locking applications. Maintenance technicians, millwrights, and mechanical assemblers regularly specify this fastener type for both OEM builds and field repairs.

Key Features

• M5 x 0.80 thread with 20 mm overall length for precise metric fitment
• Cup point geometry for firm bite and positive locking against shafts and surfaces
• Grade 14.9 (45H) alloy steel for high tensile strength in demanding applications
• DIN 916 standard compliance ensures interchangeability with metric tooling and hardware
• 2.50 mm hex key drive for installation in recessed or confined spaces
• Packaged in quantities of 50 to support production and maintenance stock needs

Compatibility

Designed as a standard DIN 916 metric set screw for use in any tapped M5 x 0.80 threaded application requiring a cup point, headless fastener.

Installation Notes

Installation should be performed by a qualified mechanical technician or assembler. De-energize and lock out any machinery before installing or replacing set screws in rotating assemblies. Use a properly sized 2.50 mm hex key to avoid rounding the drive socket. Do not exceed the design torque capacity of the thread engagement length for the mating material.
