Automotive Sector

The modern automobile is a complex technical system employing subsystems with specific design functions. Some of these consist of thousands of component parts that have evolved from breakthroughs in existing technology or from new technologies such as electronic computers, high-strength plastics, and new alloys of steel and nonferrous metals.

The growing demand for electric vehicles is a factor favoring the automotive fastener market growth. Fasteners are not only needed in electric vehicles but also in charging units, battery casings, and general infrastructural equipment. A rise in requirement for low emission commuting together with the government supporting zero emissions, long-range vehicles via tax rebates, and subsidies have propelled players to provide electric vehicles globally. Automotive fasteners play a major role in terms of new & specific applications, surrounding electrification and unique technical requirements.


The growing automobile industry and the essential significance of fastener in different vehicles are key aspects of the market. In addition to this, mechanical advancements, sturdiness of fastener, and enhancement in quality are boosting market elements. The ease of replacing fastener from vehicles enables the end-users to acquire fastener for their vehicles. Moreover, the heightening demand for lightweight vehicles and the demand’s stability will shift inclination toward automotive fastener compared to welding.

12 Point Flange Bolt

The 12-point bolt head design means that this screw can be tightened with a 12-point socket wrench which allows higher torques to be applied as compared to a standard internal hex drive socket head cap screw. This feature, combined with the larger bearing area under the head of the flange design provides further benefits over a traditional hex head cap screw.

Button Head Socket Bolt

Button head socket cap screws are also known as round head or dome head socket screws. They are manufactured with a smooth, slightly rounded dome at the head, which tends to be somewhat larger and more bulbous than standard cap screw varieties.

Often, this means that a button head socket screw can accommodate a larger gauge of hex key or driver, and thus can be affixed with more torque to achieve greater clamping forces.

CSK Socket Bolt

Also known as a flat-head screw, a countersunk screw is a type of screw that's designed to rest flush with the object or surface in which it's inserted. They are called “countersunk screws” because they “sink” into objects and surfaces. They feature a flat head that tapers along the shaft

Nib Bolt

Flat Countersunk Nib Bolts are threaded fasteners with a flat head and are tapered underneath the head. The Nib bolt has a nib which protrudes from the taper that will fit into a countersunk hole with a slot in it which is designed to hold the nib in place as the nut is tightened or loosened on the bolt.Flat Countersunk Nib Bolts are designed to sit flush on a surface.

They are commonly called Plow Bolts as they are often used to affix a blade to the edge of a plow.
