[ PROJECTION WELD SCREWS - M74 & M75 ]
   

Easy-Spot "74" Inch and "75" Metric Spot Weld
Screws have a flat spade at 90° to the threads.
The flat spade surface permits the use of
various electrode tips often utilizing the same
settings and equipment used for other spot
welds. This part may be welded to or through
other metal surfaces. May be used in confined
areas or where an offset is required.
