Manufacturer Description

Socket head cap screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or socket. MulWark 4 Size Each 25pcs Socket Head Macro M3 Fastening Cap Screws are your best choice to create a strong, stable joint, and irreplaceable in applications with limited access:

? Hex-shaped recesses in the head provide a driving surface that has increased protection against damage and has six sides of contact surface for more torque

? As compared to ordinary fasteners, less socket screws of the same size can achieve the same clamping force in a joint

? As fewer screws are required for a given job, fewer holes are required to be drilled and tapped, and there is weight reduction as well

? Mechanical properties and closely controlled manufacturing processes are even enhancing the fatigue resistance of MulWark hex socket head cap screws

? The black oxide finishing provides very mild protection against corrosion and the screws has an oil film added for additional protection
