J.W. Winco, Inc., a supplier of standard industrial machine components, announced it now offers EN 5337.9 Technopolymer Plastic Lockable Safety Five Lobed Knobs, With Tapped Brass Insert, in metric sizes.
These RoHS-compliant safety five lobed knobs are temperature resistant to 100°C (215°F), as well as resistant to solvents, oils, grease and other chemical agents. To engage and release, the key must be inserted and turned by 180°, creating a formlock between the handle and the tapped insert. Turning the key back by 180° will release the connection. The key can be inserted and pulled off in both end positions, and two keys per knob are included.
The hand knob is made from a special glass-fiber reinforced technopolymer plastic featuring a black matte finish, with the underside plastic cover ultrasonically welded to the handle body. The tapped insert is brass, molded-in, with a zinc die cast lock mechanism, while the key is brass and nickel plated, with a plastic grip.
