RS PRO Black Acetal Knurled Clamping Knob, Unthreaded Hole, Knob Diameter 26 mm, Thread Length 8mm 771-695

RS PRO 771-695 is a black acetal knurled clamping knob featuring an unthreaded hole and a knob diameter of 26 mm. Manufactured from Dupont's high-performance acetal resin, Delrin, this thermoplastic knob offers excellent tensile strength, stiffness, and resistance to creep and fatigue, while remaining lightweight.

The knurled surface is engineered to provide superior grip and allow precise adjustments in a variety of industrial and mechanical applications. Its 8 mm thread length is designed to accommodate multiple socket head cap screws, enabling self-assembly for custom length control. It is recommended to use a stop or spacer equivalent to the screw head diameter to avoid over-pressure.

The knob operates reliably across a temperature range of -40°C to +120°C, ensuring durability in harsh environments. It is primarily used in fabrication machinery, clamps, fixers, storage solutions, and general furniture where controlled tightening, loosening, or positioning is required.

These knobs support multiple socket head cap screw sizes including M3, M4, M5, M6, and M8 variants, providing flexibility for different mounting needs. The compact low height design is suitable for applications in restricted spaces without compromising functionality.
