What type of bolts are used on cars?
Bolts are an essential component in the construction and maintenance of vehicles. They hold together critical parts of a car, ensuring safety, durability, and performance. In this article, we’ll explore the different types of bolts used in cars, their purposes, and why choosing the right bolt is crucial for automotive applications.
Types of Bolts Commonly Used in Cars
Cars rely on a variety of bolts, each designed for specific applications. Here are the most common types:
- Hex Bolts: These are the most widely used bolts in automotive applications. Their hexagonal heads make them easy to tighten and loosen with standard tools. They are often used in engine assembly and chassis construction.
- Carriage Bolts: Recognizable by their rounded heads and square necks, carriage bolts are typically used in areas where a smooth, finished appearance is desired, such as securing body panels.
- Flange Bolts: These bolts have a built-in washer-like flange under the head, which helps distribute pressure evenly. They are commonly used in engine and transmission assembly.
- Stud Bolts: These are threaded rods without a head, often used in applications where a nut is required on both ends, such as securing cylinder heads.
- U-Bolts: Shaped like the letter "U," these bolts are used to secure pipes, exhaust systems, or suspension components.
Materials Used for Automotive Bolts
The material of a bolt is just as important as its design. Automotive bolts are typically made from the following materials:
- Steel: The most common material, steel bolts are strong and durable. They are often coated with zinc or other materials to prevent corrosion.
- Stainless Steel: These bolts are highly resistant to rust and corrosion, making them ideal for use in areas exposed to moisture or chemicals.
- Aluminum: Lightweight and corrosion-resistant, aluminum bolts are used in applications where weight reduction is a priority, such as in sports cars.
- Titanium: Known for its strength-to-weight ratio, titanium bolts are used in high-performance and racing vehicles.
Why Choosing the Right Bolt Matters
Using the correct type of bolt is critical for the safety and performance of your vehicle. Here’s why:
- Safety: Bolts hold together essential components like the engine, suspension, and brakes. Using the wrong bolt can lead to failure and compromise safety.
- Durability: Automotive bolts are designed to withstand specific stresses. Choosing the right bolt ensures longevity and reduces the risk of wear and tear.
- Performance: High-quality bolts contribute to the overall performance of the vehicle by maintaining proper alignment and structural integrity.

Frequently Asked Questions
What kind of bolts to use on cars?
Bolts must be durable, so they're made from strong materials, such as steel and stainless steel, that resist corrosion. Titanium is becoming increasingly popular for electric vehicles and other vehicles because they're strong and lightweight.
What grade bolts for automotive use?
grade 8 bolts
You will often find grade 8 bolts in demanding applications, such as in automotive suspensions. Other applications that require the strength and tolerance of a grade 8 bolt are industrial machinery, motors, pumps, valves and tanks!
How do you tell if a bolt is SAE or metric?
This one numbers on top 8.8 metric this one's so dirty i can't see. It. This also has numbers on the top it's going to be metric 8.8 that one says here's one says 10.9.
Do cars use metric or sae bolts?
Even today's modern cars continue to use metric fasteners as the standard because they have various decimal dimensions instead of inches like standard measurements. Even American-made cars use metric bolts.
What material are car bolts made of?
Metal Fasteners: Iron or aluminium alloy is the most common material in automotive projects. Typically the most durable and reusable material, most bolts are covered in zinc for rust protection and durability.
What type of bolts to use on cars?
Bolts must be durable, so they're made from strong materials, such as steel and stainless steel, that resist corrosion. Titanium is becoming increasingly popular for electric vehicles and other vehicles because they're strong and lightweight.
Are grade 8 bolts good for automotive?
Few fasteners can match the strength and reliability of Grade 8 bolts. For that reason, they're very common and play a critical role in various industries, from automotive and construction to heavy machinery and manufacturing.
What is the most common bolt on a car?
Hex-head automotive bolts and screws are the most common automotive fasteners. They have a six-sided head or hexagonal (hex) head, with the bolts having a shank while the screws have a full threading profile.
Are car lug nuts metric or standard?
Lug nuts often differ between domestic and import models as sizing varies between SAE and metric. As well, the vehicle type can make a difference for the sizing as larger cars, trucks, and SUVs tend to have larger diameter studs, thus bigger lug nuts.
What is bolt pattern for cars?
Bolt patterns are usually expressed in two numbers: the number of lugs on the wheel and the distance between each lug in inches. For example, a 5x100 bolt pattern means the wheel has five lug holes, and the distance between each lug is 100 millimeters.
