Value Collection SS6X12040-025BX Set Screw M12 1.75 40mm

Product Description

The VALUE COLLECTION SS6X12040-025BX is a metric cup point set screw designed for mechanical assemblies requiring a corrosion-resistant fastener. Manufactured from 18-8 austenitic stainless steel to Grade A2, this screw meets DIN 916 standards and is driven with a 6 mm hex key. The M12 x 1.75 thread pitch and 40 mm overall length make it suited for medium-to-heavy shaft-collar, gearbox, and fixture-clamping applications where the cup point bites into the mating surface to resist rotation and axial movement without a projecting head.

This set screw is used in industrial, mechanical, and trade applications where a flush or recessed fastener is required. Typical install scenarios include securing collars to shafts, locking pulleys or sprockets in position, and anchoring components in HVAC equipment frames, pump assemblies, and electrical enclosure hardware. The stainless steel construction makes it appropriate for damp, washdown, or mildly corrosive environments where carbon steel fasteners would be unsuitable.

Key Features

• M12 x 1.75 metric thread with 40 mm overall length for deep thread engagement
• Cup point geometry grips shaft surface to resist torque and axial displacement
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant for wet or outdoor environments
• Conforms to DIN 916 fastener standard for dimensional consistency
• Internal hex drive requires a 6 mm hex key — no protruding head for flush installations

Compatibility

Designed as a DIN 916-compliant metric set screw for use in any M12 x 1.75 threaded bore requiring a cup point, headless configuration.

Installation Notes

Installation is typically performed by a mechanic, millwright, or qualified technician using a 6 mm hex key or hex-drive bit. De-energize and lock out all rotating or powered equipment before installing or removing set screws per applicable LOTO procedures. Do not exceed the rated torque range for M12 stainless fasteners and avoid over-tightening, which can gall stainless threads — applying an anti-seize compound appropriate for stainless steel is recommended. Verify thread engagement depth meets the requirements of the assembly design before returning equipment to service.
