The Loosening Resistance Of Ordinary Bolts And Nuts

At present, most of the fastening connections used for vehicles are ordinary hexagon bolts, hexagon nuts, spring washers, and other fasteners. In order to let you know more about the connection of bolts and nuts for vehicle fasteners, as a professional fastener manufacturer, Xinchi Fastener Company is pleased to share the loosening resistance and failure analysis of ordinary bolts and nuts, and a comparison of several locking nuts for the vehicle.

Let’s first introduce the anti-loose situation of ordinary bolts and nuts.

Bolt anti-loose structure types mainly include: hexagonal flange face bolt, which increases the contact area; Hexagonal flange bearing face with tooth bolt, which increases the contact area and increases the friction coefficient; Hexagonal head bolt with hole and hexagonal head butterfly bolt with a hole is mechanically locked by steel wire after assembly.

The main structure types of nuts are: hexagonal flange nuts to increase the contact area; Hex lock nuts for non-metallic inserts and hex flange nuts for non-metallic inserts to prevent loosening through inserts; Hexagon slotted nuts are mechanically protected from loosening by means of cotter pins.

The function of the washer’s anti-loosening structure is to prevent loosening and increase the elasticity, and the form is mainly the spring washer, conical elastic washer, outer sawtooth lock washer and so on. In the construction, it is also often used to glue thread or mechanical locking anti-loosening measures, the latter such as hole bolts with iron wire fastening, locking pieces, etc.
