JW Winco, Inc., a Ganter Company and supplier of standard industrial machine components, announced the offering of GN 653.2 steel & stainless steel flat knurled thumb screws with recessed stud for loss protection.
The thumb screws, which are RoHS compliant, can be used to prevent loss of the thumb screw, due to the recessed portion of the stud. When using, instead of a typical tapped and bored hole, it is necessary to provide tapped bores with a thread on each of the two elements to be assembled. Additionally, a clearance bore on one or both sides is required.
Depending on the design and required clamping length of the component being attached, there are a number of assembly options. The steel knurled thumb screw body with a black oxide finish has tensile strength of class 5 and the visible face is fine turned. The stainless steel version is made of 303 stainless steel and comes with a matte, shot-blasted finish.
