How to Tighten Nuts and Bolts Properly

Don’t over-tighten nuts and bolts 

One of the most common DIY mistakes is assuming that tighter always means stronger. However, over-tightening can weaken fixings and damage the material they are securing. 

When tightening Buts, Bolts and Setscrews, excessive force can stretch or weaken the threads, making them more likely to fail under load. Over-tightening can also crack fittings or crush softer materials. 

How to avoid it: 

In some situations where the correct tightening torque is crucial, use a Torque Wrench! Otherwise, tighten fixings until they are secure, then stop. If resistance suddenly decreases, it’s often a sign the thread has stripped. 

Don’t forget to use a washer! 

Washers may seem optional, but skipping them can be a cause of fixing failure. Without a washer, the load is concentrated on a smaller area, which can lead to fixings pulling through the material or working loose over time. 

Washers can also help prevent damage to painted or finished surfaces and allow nuts and bolts to tighten more evenly. 

Build Stronger, Longer-Lasting DIY Projects 

Most fixing failures come down to simple errors that are easy to avoid with the right knowledge. Avoid over-tightening, choose fixings that suit the material, and never overlook washers. Small details make a big difference, and using the correct hardware from the start will save time, money, and frustration on future repairs.
