Model: M20 x 130 mm Screw Pitch: 2.5 mm Screw Length: 130 mm Left Thread Length: 43 mm Key benefits - Deep engagement for strong mounting in machinery and equipment. - Left thread segment (43 mm) supports locking configurations to help resist loosening in certain rotating or vibrating applications. - 2.5 mm pitch provides smooth threading and repeatable preload for consistent performance. - Total length of 130 mm gives room for deep engagement while fitting in thick components. - Standard M20 dimensions support compatibility with compatible threaded holes and assemblies. What makes it stand out - Combines a long 130 mm length with a dedicated left hand thread section for versatile installation options. - Clear specifications (diameter, length, pitch, left-thread length) support reliable sourcing and replacement. Compatible applications and scenarios - Machinery and automation frames where deep engagement and a locking left-thread segment improve stability under vibration. - Heavy equipment panels, guards, or housings that require a long fastener to reach through thick components while maintaining clamping force. - Automotive or industrial assemblies needing a fastener with a left-hand threaded portion to reduce the risk of loosening during reverse torque conditions. Usage tips - Ensure an M20 threaded hole or nut is used for proper mating. - Use appropriate tools to achieve the intended preload without over-tightening.
