Bolt, mechanical fastener that is usually used with a nut for connecting two or more parts. A bolted joint can be readily disassembled and reassembled; for this reason bolts or screw fasteners are used to a greater extent than any other type of mechanical fastener and have played an important part in the development of mass-produced articles and steel structures.
The bolt consists of a head and a cylindrical body with screw threads along a portion of its length. The nut is the female member of the pair, having internal threads to match those of the bolt. Washers are often used to prevent loosening and crushing. See also nut; washer.
How Is a Bolt Made?
FEATURE 01
Cold forming is the process of forming a bolt without heating up the material. It’s accomplished by striking or pressing the material in a die to create desired dimensions
FEATURE 02
Hot forging is the process of heating up material to a point where it becomes malleable, then forming it in a die.
FEATURE 03
Machining is the process of using machinery to cut away material until it fits desired dimensions.
Each of these bolt manufacturing processes has its own pros and cons, which you can read about in this article. We use cold forming most often at Wilson-Garner, as we believe it to result in the strongest and highest quality products. However, we also use machining when it makes sense to do so.
Common Types of Bolts
There are many types of bolts, all with different features and use cases. Below is a list of the most common types.
- Place bolts feature self-locking, free-spinning hex heads that prevent loosening due to vibration. Read more about them here.
- Carriage bolts feature reduced body diameters and enlarged, domed heads.
- Hex bolts feature six-sided hex caps on one end. Read more about them here.
- Flange bolts feature washers on the underside of their heads, which help distribute the force from bearing loads more efficiently.
- Shoulder bolts feature a smooth, cylindrical shoulder between their heads and threaded sections. The shoulder is usually larger in diameter than the threaded portion, serving as a guide for the rotation of a mating part.
- Machine bolts feature a square head on one end and a semi-cone point on the other.
- Custom bolts, also known as special bolts, are specifically designed and manufactured for a particular use. Check out our custom bolt manufacturing capabilities here.

Bolt grades explained: Metric
Metric bolt grades are known as “property class,” and are set by the International Standards Organization (ISO). This system uses two numbers separated by a dot expressed in raised or depressed numbers either on the top or side of the bolt head. The higher the ISO numbers, the stronger the bolt.
Stainless steel bolt grades refer to the grade of stainless steel to make bolts. Stainless steel bolt strength grades are typically made of 304, 316 or 410 stainless steel. They’re bolt heads are marked as either A2 or A4.
Metric bolt grades and uses
| Grade 8.8 |
Commonly used high-tensile bolt grade include the following applications: Automotive – engine components, chassis assembly, suspension systems, & critical structural connections Machinery & equipment for securing critical components subjected to high loads, vibrations, & harsh operating conditions Construction for structural engineering uses, such as bridges |
|---|---|
| Grade 10.9 |
Even stronger than grade 8.8: Heavy machinery, such as construction & mining equipment, agricultural machinery, and other heavy-duty applications Construction – structural steel connections that require high strength, such as bridges Automotive and racing, such as engine assemblies, suspension systems, & chassis components |
| Grade 12.9 |
This high-tensile bolt grade can handle all of the above, plus: Aviation for secure fastening for components in aircraft structures, engines, landing gear, & other high-stress areas Heavy machinery & equipment, construction machinery, mining equipment, offshore drilling rigs, & other heavy-duty applications Oil & gas for critical applications such as offshore platforms, pipelines, pressure vessels, & refineries |
| Grade A2 |
304 stainless steel bolts are used for: Food processing equipment for excellent corrosion resistance and hygiene properties. Used for securing equipment, conveyors, and components that come into contact with food or beverages |
| Grade A4 |
316 stainless steel bolts are typically used in: Marine environments due to superior corrosion resistance, particularly in saltwater environments. Used in boat building, dock construction, & other marine structures exposed to harsh conditions |
