A useful tool when an exact torque value is needed in engine assembly. Some engines with stretch bolts (rover k-series for example) require the head bolts to be gradually torqued in sequence using an angular torquing value rather than a torque value itself (Nm etc). This can be a rather daunting task, especially when trying to be accurate multiple times. This is where an angular torque gauge comes in.
This easy-to-read angle gauge is accurate to 2°. Dual-length locking arm holds body in place. Compatible with non-impact 1/2" drive tools.
