Nuts and Bolts: Four Fundamental Guidelines for Preventing Seizing

If you are planning on replacing the nuts and bolts in your equipment, you should think about the risk of seizing. Removing fasteners is difficult when seizing occurs, and it can cause damage to the equipment. Usually, the problem can be attributed to the threads of the nuts and bolts welding together due to heat and friction. The compromised fastener could cause a lot of trouble during future maintenance and repairs. Here are simple tips to keep in mind when replacing your nuts and bolts to prevent seizing.

Purchase with Care

Choose the right nuts and bolts for your needs. Unsuitable fasteners are more likely to get stuck during and after installation. In general, the best approach to choosing these products is acquiring a replacement that matches the original installed by the equipment manufacturer. You can type-match the installed fastener after removal, check the manual or consult the manufacturer. The critical specifications for selection include sizing, fabrication material, bolt and nut design and installation method.

Use a Lubricant

When purchasing your nuts and bolts, consider picking an anti-seizing lubricant. This choice is particularly beneficial when dealing with stainless steel fasteners. These units have a protective coating that prevents deterioration due to oxidation. Unfortunately, the layer increases the frictional forces in the fastener assembly, increasing the risk of seizing. You can minimise friction by using a little lubricant before placing the nuts and bolts. The oil layer will also minimise fastener deterioration.

Consider the Torque

Installing bolts and nuts is not difficult. However, it is not uncommon for people to tighten the fasteners too much. The goal of overtightening is to ensure that the assembly does not come apart when the equipment is in use. Unfortunately, this precaution can be highly harmful. Excess force could compromise the threads, causing seizing. Moreover, the damaged threads will necessitate the replacement of the fasteners within a short period. Therefore, check the maximum recommended torque for installing the units. Do not exceed the indicated force, and always use the suggested tools for installation.

Choose Washers

Finally, plan on using washers for your nut and bolt assembly. Washers are designed as disk-like units, and they promote proper installation and minimise seizing risks. Moreover, the placement of the product will improve fastener function by distributing pressure, increasing protection for the equipment and ensuring the stability of the bolts and nuts. There are multiple types of washers available, including flat, bevelled and structural. Choose the most compatible with your equipment and fasteners.
