Six self-captivating M4 stainless steel machine screws thread into integral stainless steel bushings; the recommended torque for this size is 8-9 lbf-in (90-100 cN-m). The preformed high temperature silicone gasket is replaceable. Internal DIN rail tabs, M3 brass inserts and standoffs, and card guides for 1.5 mm PC boards are molded in.
