Palnut® Capped Washer - Self-Threaders
Non-Threaded Applications
Palnut self-threading nuts and Pushnut® fasteners are respectively turned on and pushed on non-threaded projections, or "studs". These fasteners eliminate the cost of cutting threads and the problems of cross-threading. They permit simpler, more economical and ultimately better designs.
With these fasteners, there is no thread to find and no binding from dirt or damaged threads. Because of their prevailing torque, the fasteners provide excellent vibration resistance.
Stud materials, which must be appreciably softer than that of the fasteners, include die cast zinc,aluminum, molded plastics, steel and brass.
The Dimensions of the following parts are envelope dimensions only. For complete design information, please contact us.
Note:
Parts SP330012 and SP30016 are only for use on tough plastic such as ABS or polypropylene for
which 45-50 in. lbs. torque develops approximate 100 lb. tension.
*At the tooth-engagement point when the fastener is seated, stud tolerance is + or - .003".
