Square conical washer SEMS machine screw torx pan head stainless steel

Square conical washer SEMS machine screw features an integral, free-spinning, Square Cone (Square Dome) washer. With two distinct configurations, this dual action spring washer has two separate load deflection rates. The configurations act in unison to provide a reliable low-torque, controlled tension fastener. The Square Cone (Square Dome) Sems assembly provides a higher retained clamp load and improved compensation for thermal cycling and vibration. This fastener is capable of accepting a high tension load while maintaining alive spring action and generates a constant load, even with variations in installation torques. By increasing the acceptable driving torque range, it enhances flexibility in component design. The Square Cone (Square Dome) washer’s long deflection period and two-stage loading contribute to better control during installation, improve tool bit life and reduce operator fatigue. Load is directed toward the outer diameter of the washer, making the fastener ideal for clamping fragile materials and preventing stress cracking problems around clearance holes. Ever Hardware provides custom made square conical washer SEMS machine screw and customizable packaging.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture.
