Industrial Applications

  • Electrical Panels and Assemblies: Our stainless steel grub screws are engineered to fit into electrical panels, collars, and shafts, providing secure connections that do not slip or loosen even in the face of vibration or load.
  • Automotive industry: As a reputed grub screw manufacturer in India, we offer robust gear, pulley, and collar mounting solutions that ensure the close fit of fasteners on shafts in high-speed, high-torque applications.
  • Machinery and equipment: Our alloy grub screws ensure reliable locking of rotary parts and mechanical assemblies, ensuring continuous or heavy-duty operations without loosening.
  • Precision instruments: As a dedicated precision grub screws manufacturer, we deliver compact, headless fasteners ideal where space is limited, offering flush or recessed fastening without compromising accuracy or performance.
  • Appliances and consumer products: Available in mild steel grub screws and custom size grub screws, these fasteners are widely used where a clean, low-profile, or hidden fastening solution is needed, maintaining aesthetic appearance while ensuring structural integrity.

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.
