Value Collection 832010PR Set Screw M3x0.5x12mm

Product Description

The VALUE COLLECTION 832010PR is an M3 x 0.50 x 12 mm flat point set screw manufactured from alloy steel at Grade 14.9 (45H). Set screws of this type are fully threaded, headless fasteners used to secure components — such as collars, gears, pulleys, and knobs — against a shaft or within a bore. Drive engagement is via a 1.5 mm hex key socket. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity. This screw conforms to DIN 913 and ISO 4026 dimensional standards, ensuring consistent fit in metric-toleranced assemblies. Installation and maintenance technicians across mechanical, HVAC, electrical, and industrial trades rely on this fastener type for compact, low-profile clamping applications.

This set screw is suited for light-duty mechanical assemblies where a flush or sub-flush fastener is required. The flat point style distributes clamping load across the contact surface without marring soft shaft materials as aggressively as a cup or cone point. Typical applications include securing set-position collars on motor shafts, locking adjustment knobs on valve stems, and positioning small mechanical components in tight-clearance housings. The metric M3 x 0.50 thread pitch and 12 mm overall length make it appropriate for thin-walled hubs and compact bracket assemblies common in residential and light commercial equipment.

Key Features

• M3 x 0.50 metric thread with 12 mm overall length for compact fastening applications
• Flat point design distributes clamping load and reduces shaft marring
• Alloy steel construction at Grade 14.9 (45H) for high tensile and torsional strength
• 1.5 mm hex key drive for installation in restricted-access locations
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Conforms to DIN 913 and ISO 4026 dimensional standards for metric fastener interchangeability

Compatibility

Designed as a standard metric set screw conforming to DIN 913 and ISO 4026, suitable for any threaded M3 x 0.50 bore requiring a flat point, headless fastener in alloy steel.

Installation Notes

Installation is performed with a 1.5 mm hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize or lock out any equipment and remove rotational load from the shaft before installing or adjusting set screws. Do not exceed the rated torsional capacity of the M3 thread; overtightening a fine-pitch metric set screw can strip the thread or fracture the fastener. Follow applicable machinery safety standards and equipment manufacturer guidelines for fastener retention requirements.
