J.W. Winco Expands Line to Include Safety Lobed Knobs with a Steel Tapped Insert
January 30, 2009
NEW BERLIN, WI -- J. W. Winco, Inc., a leading supplier of standard industrial machine components, announced it has expanded its offerings to include GN 5337.3 series plastic Safety Lobed Knobs with a Steel Tapped Insert.
The RoHS-compliant hand knob is constructed of special glass fiber-reinforced technopolymer plastic with a black matte finish. The tapped insert, screw, and spring are made of steel in a black oxide finish. The molded-in inlay is zinc die-cast.
Available in metric and inch sizes, these knobs are best suited for applications where any unintended loosening of the knob may lead to accidents. In non-operative mode, the lobe knob is not engaged with the tapped insert, so it may be turned easily. Only after axial pushing of the knob does it engage with the insert so that the knob may be tightened or loosened. After release, the serrations disengage by means of a spring. The five lobe design is visually appealing and also gives the operator the means to achieve higher torque.
The knobs are temperature resistant to 130°C (355°F). They are resistant to solvents, oils, grease, and other chemical agents. Versions with stainless steel inserts or with colored cover caps are available upon request. Other modifications, such as cross holes, set screw holes, and threaded studs, are also offered.
J.W. Winco offers an extensive selection of inch and metric size adjustable levers, cabinet U-handles, plastic and steel hinges and locking mechanisms, revolving and retractable handles, hand wheels, hand cranks, conveyor components, leveling mounts, hand knobs, spring, ball and indexing plungers, jig, fixture and fastening components, toggle clamps, metric casters and wheels, universal joints, oil sight glasses, and metric tools for the industrial and commercial equipment industries.
