Remember at RPTS we calibrate, certify and sale torque and precision hand tools.

Business has been good because of you.  Many people have been asking what we have been up to, so this last year we have been meeting new and existing customers at regional trade-shows.  It is great to showcase our capabilities for the public, remember at RPTS we calibrate, repair, sale and consult on precision hand tools and torque wrenches up to 2,000 ftlbs.

Hope to see you soon.

Here is the formula:

RS = Torque setting of the torque wrench.

A = Distance from the center of the square drive of the torque wrench to the center of the handle grip pull point.
B = Length of the adaptor from the center of the square drive to the center of the nut or bolt. Use only the length which is parallel to the handle. See figure 1
T = Torque desired. This is the actual torque applied to the fastener. Here is a typical problem: What should the setting be when ‘‘A’’ is 12’’, ‘‘B’’ is 6’’ and ‘‘T’’ is 30 Ib. ft.

Therefore 30 pound foot of Torque will be applied at the fastener when ‘‘RS’’ is 20 pound foot.

Note: If the torque wrench reads in pound foot, then ‘‘T’’ should also be in pound foot. ‘‘T’’ and ‘‘RS’’ should be in the same unit of measurement. ‘‘A’’ and ‘‘B’’ should also be the same unit of measurement.
