Product Description

As a leading manufacturer in India, we supply threaded fasteners without an external head, designed to be driven by wrenching an internal socket or slot. Commonly used to lock parts like collars or gears on shafts, these fasteners are available in multiple point types — flat, cone, cup, dog, or knurled — to suit the holding force and surface protection required. Our range covers various materials and finishes, ensuring every fastener delivers consistent performance, corrosion resistance, and strength in demanding mechanical assemblies needing secure, low-profile fastening solutions.
