Review on Enhanced Power Transmission Products with Threaded Backlash Spring - Sunhokey by Jon Garcia

later These GAP blocks are very well made and cost money to remove LEADSCREW's GAP. The THREAD machined into two half nuts is a 2mm STEP FOUR START, which I was not aware of when ordering the units BUT AMAZON's online returns make any return a breeze. SUNHOKEY ANTI-LASH SPRING NUTS is what you need when you have a FOUR WAY SCREW. The parameters I got back from SUNHOKEY C/S were as follows: PITCH 2mm, PITCH 8mm and the formula PITCH = 4 x PITCH which gives 4 STARTING NUTS WITH ANTI-ZARD. Thanks to AMAZON and SUNHOKEY for the professional CUSTOMER SERVICE that really makes the BUYER to SEARCH and BUY what they need again.
