The Mitee-Bite 31750 is a high-performance 1/4-20 screw size expansion clamp engineered for precise internal workholding and reliable fixture positioning. Manufactured as a 17-4PH stainless steel expansion pin, it offers exceptional durability and resistance to wear in demanding machining environments. This Mitee-Bite expansion locating pin provides accurate positioning and repeatability, making it ideal for precision setups. With a holding force of up to 1900 lbs, it ensures secure clamping during machining operations. The expansion mechanism allows the pin to expand within the bore, creating strong internal gripping without external obstruction. This makes it highly effective as a secondary operation workholding pin where full surface access is required. The modular design supports use in grid plate expansion pin systems and tombstone fixtures. Its compact profile enables a multi-size press fit pin system approach, allowing flexible integration into various setups. The pin operates with a maximum torque of 13.3 ft-lbs, ensuring controlled expansion and reliable locking. Made for efficiency, it reduces setup time while maintaining high precision. The expanding diameter capability enhances contact within the bore, improving stability during cutting processes. It is suitable for CNC machining, milling, and fixture-based operations. The stainless steel construction ensures long service life and consistent performance. This pin also functions as a reliable M12 press fit fixture locating pin alternative in compatible setups. The Mitee-Bite 31750 is an ideal solution for modern, high-precision workholding applications.
