The M4 x 40mm Allen Socket Head screw is 4mm in diameter and 40mm long. When using a socket head cap screw, you don't need external clearance like you do with hex head bolts, making them perfect for tight spaces. They also provide a higher torque and clamping force compared to regular screws. Made from high-quality Stainless Steel 304 (SS304), these screws offer excellent resistance to corrosion and wear, ensuring long-lasting durability and reliability

It can be used in:

• Machinery Assembly: Socket head screws are used to secure components in machinery, providing a stable and reliable connection.
• Automotive Applications: These screws are essential in automotive applications, securing components to ensure vehicle safety and performance.
• Electronics: Ideal for electronics, socket head screws secure components firmly in drones, robots and 3D printers.

Socket head cap screws are designed with a hexagonal internal drive in the head, allowing them to be tightened and loosened with an Allen key.
