Pan Head Socket Screw Manufacturer | Custom Precision Fasteners

Pan head socket screws are a type of fastener characterized by a pan-shaped head with a hexagonal recess (socket) for driving. Unlike standard pan head screws that use a Phillips or slotted drive, socket head cap screws (often called Allen screws) have a cylindrical head. However, pan head socket screws combine a pan head profile with a hex socket, offering a unique blend of low profile and high torque capability. This design is particularly valued in applications where a protruding head is unacceptable and high tightening torque is required without cam-out. At our company, we produce pan head socket screws through a multi-stage process: raw material selection, cold heading or hot forging to form the head and shank, thread rolling, heat treatment (if required), CNC machining for critical dimensions, and surface treatment. Our 630T and 300T forging machines enable the production of larger diameters, while our 10 multi-station cold heading machines efficiently produce high volumes of smaller screws. With over 100 CNC lathes and 50 machining centers, we can machine the socket and head to precise tolerances, ensuring proper fit and function. We also offer secondary operations like drilling, milling, and turning to create custom features. Quality control is paramount: we use advanced metrology equipment to verify dimensions, thread pitch, and mechanical properties. Our pan head socket screws are used in automotive, aerospace, electronics, and industrial equipment. We understand that different markets have varying standards; we can manufacture to DIN, ISO, ANSI, JIS, and GB standards. Our team works closely with clients to understand their specific needs and provide tailored solutions. Whether you need a standard pan head socket screw or a fully custom design, we have the expertise and capacity to deliver.
