USAG 1/2" Drive Torque Wrench w/o Ratchet Head or Accessories (20-100nm , 15-75 ft lbs)(S.306-100D) - The wrench body is the heart of a highly flexible system (9x12mm accessories can be purchased separately) which enables the accurate torquing of fasteners, including those in tight spots that cannot be accessed with a socket. A pivot knob with a 72-tooth ratchet head can be used to stabilize the wrench in line with the fastener being tightened. Wrench is a micrometer type with automatic reset when pressure is released to ensure the tool is ready for the next fastener. Includes plastic storage case. Accuracy to +/-2% . Made in Italy. Includes calibration certificate.

I feel the 306 series (USAG brands it as their 811 LB series) is the best all around torque wrench that USAG/Facom makes today. Great accuracy without potential electronics issues with some of the more costly units. Plus you've got the option of using the open end or ring end attachments when a ratchet/socket approach is not an option.
