Part 11: Tightening a fixing is a matter of technique
Depending on the type, fixings are tightened manually or with a mechanical screwdriver, torque or Allen wrench or a fixing-specific installation tool. Using the correct tightening torque Tand installation tools makes installation easier and saves you from unnecessary work, over- or undertightening, breakdown of threads and any cracking of the fixing base. Remember that a correctly sized and carefully cleaned drill hole makes tightening easier!
