Value Collection SS6X16025-025BX Set Screw M16x2 25mm Cup Point

Product Description

The VALUE COLLECTION SS6X16025-025BX is a metric set screw designed for industrial and mechanical fastening applications where a flush or recessed installation is required. It features a cup point tip that bites into mating surfaces to resist rotation and axial movement without the need for a protruding head. The screw is manufactured from Grade 18-8 austenitic stainless steel meeting the A2 material designation under DIN 916, offering solid corrosion resistance in moderately harsh environments. The thread size is M16 x 2.00 with an overall length of 25 mm, driven by an 8 mm hex key. Machinists, maintenance technicians, and assembly professionals are the typical installers.

This set screw is suited for use in shaft-to-collar connections, shaft couplings, handwheels, pulleys, and similar mechanical assemblies where a headless fastener is needed to secure a component to a shaft. The cup point creates a shallow indent on the shaft surface, providing positive retention. It is appropriate for light to moderate torque applications in environments where mild corrosion resistance is a priority, such as food processing, marine auxiliary equipment, or general manufacturing. The metric M16 x 2.00 thread pitch is the standard coarse pitch for this diameter class.

Key Features

• Cup point geometry creates a localized impression on the shaft for reliable hold against rotation and axial movement
• M16 x 2.00 metric coarse thread with 25 mm overall length
• Grade 18-8 stainless steel, Austenitic Grade A2, for corrosion resistance in wet or mildly corrosive environments
• Headless hex socket drive per DIN 916; requires an 8 mm hex key
• Fully threaded along the 25 mm length for maximum engagement depth flexibility

Compatibility

Designed as a standard DIN 916 metric set screw compatible with any tapped M16 x 2.00 threaded bore in collars, couplings, hubs, or mechanical assemblies requiring a headless fastener.

Installation Notes

Installation requires an 8 mm hex key or Allen driver. Ensure the mating bore is clean and the thread is free of debris before installation. Apply appropriate thread lubricant or anti-seize compound for stainless fasteners to reduce the risk of galling under torque. Follow applicable mechanical assembly standards and verify shaft and bore alignment before final tightening.
