Custom Double Thread Type 17 Wood Screws

 

These custom double thread screws were a custom variation of hanger bolt for our construction customer - they were manufactured using 304 stainless steel material and combines an M6-1.0 machine screw thread that includes a 3MM hex socket drive with oversize type 17 point wood screw thread.  A needle sharp point was a prominent and critical feature accomplished with fine tuned point angle.  The parts were provided with factory passivated finish.
