Where do you find mating torque on connectors?
The MIL specs for connectors usually specify a “recommended mating torque” in the beginning of each slash sheet. Many connector manufacturers specify that value in the general specification pages for each connector series and I have not seen many inconsistencies among the various manufacturer’s.
Can a torque wrench tighten a mating fastener?
Applying torque to the mating fastener can damage the fastener, mating components or provide insufficient clamp load. There are three different methods for the specification of tightening fasteners: Torque + Angle-to-Yield (TAY) (a.k.a Torque-to-Yield (TTY)). A fastener with a torque specification can be tightened with a conventional torque wrench.
Which is the correct torque for a fastener?
* Tightening Torque (in-lbs through M8; M10 & over ft-lbs) METRIC FASTENERS Nominal Size or Basic Screw Dia. Threads per inch Tensile Stress Area (sq. in.) ASTM A574 Clamp Load (lbs) Tightening Torque K = 0.15 K = 0.17 K = 0.20 Coarse Thread Series
How to determine the torque of a socket?
A whole lot of engineering work must be done before a socket ever hits a bolt head. Engineers must determine the type and number of fasteners needed to secure the joint. They need to consider platings, coatings, lubricants and thread-lockers. They need to think about how the fastener will be installed.

What are the MIL-DTL-38999 coupling and uncoupling torquetable?
(Meets MIL-DTL-38999, paragraph 3.11) Coupling torque for mating and the uncoupling torque for unmating of counterpart plugs and receptacles, mating of connectors to and from protective covers, and mating plugs to and from dummy stowage receptacles, shall meet the requirements in Coupling and Uncoupling Torquetable. Coupling and Uncoupling Torque
When to use higher torque on a bolt?
Higher torques (up to theoretical yield) are sometimes used for bolts that cannot be locked to resist vibration. The higher load will increase the vibration resistance of the bolt, but the bolt will yield and unload if its yield point is inadvertently exceeded.
