In general, you should make the bolt tight enough so that the items it is holding together stay together, but not so tight that you damage the bolt’s threads. You should tighten bolts properly so that the bolt performs properly.
How do you know when a screw is tight enough?
So you’re on your own. We suggest you tighten the nut, bolt, or machine screw by hand until it makes contact with the washer or the surface of the workpiece. Then, using an adjustable wrench or a socket wrench, make a consistent number of turns to ensure that all the bolts have the same torque.
Can you tighten a screw too much?
Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
Should you tighten screws all the way?
One of these is that you should aim to tighten the fastener to within the limits of the fastener, and not past these limits. For instance, if a fastener has been designed to withstand a torque of 900 Nm of torque, it would be unwise to fasten it any tighter than this.
How hard should you screw?
A drywall screw should be screwed in to where the head is just barely under the paper on it’s face. They make drills, and drill accessory bits, specifically for this task. For everything else, run the screw in until your material is tight.
Do screws need to be torqued?
Why Torque Matters
Proper torqueing is vital to the function of the bolt and is determined by several, often conflicting factors. A properly tightened bolt has its material stretched slightly, but not beyond its elastic limit.
How much torque do you need for screws?
US Recommended Bolt Torque
|Grade 2||18-8 S/S|
How tight is finger tight torque?
Results: The average peak torque to achieve two finger tightness for all subjects was 0.247 N-m (std dev = 0.057). The torques ranged from 0.11 (for one PGY3 resident) to 0.32 (for one attending) N-m among the subjects.
What will happen to the screw if you over tighten them with a screwdriver?
Screws can become stripped if you over-tighten them with a screwdriver. A stripped screw, as shown in Figure 2, may get stuck in the screw hole, or it may not tighten firmly.
What are the possible effects of over torquing or under torquing?
When the joint in question is over-torqued, the flange load can become uneven and weaken the effectiveness of the flange/bolt load. This in turn leads to an increase in blow-out pressure and hydrostatic force, which can cause joint failure.
How tight should a nut be?
Getting them off a journey when you have a flat could leave you stranded, so they should be nipped up a bit more than finger tight. If the locking nut comes loose, the other wheel nuts should be fully tightened and Torqued.
What does over tighten mean?
