M5 x 16 Hexagonal head shoulder bolts A2 Black Stainless Steel

What are Hexagonal Head Shoulder Bolts?

Hexagonal-head shoulder Bolts are a type of fastener recognizable by their hexagon heads. They allow for easy installation and removal with a wrench.

These bolts are unique in that they feature a "shoulder" — a smooth, cylindrical section between the head and the threaded portion. The shoulder acts as a precise bearing surface. This design allows components attached to the bolt to rotate or slide, making it ideal for applications requiring controlled movement, alignment, or spacing between parts.

A2 stainless steel offers enhanced corrosion resistance compared to other grades of Steel, making these bolts suitable for use in environments where exposure to moisture, mild chemicals, or varying temperatures is expected. Additionally, A2 stainless steel is known for its excellent machinability, which makes it easier to produce bolts with tight tolerances, a critical factor for shoulder bolts used in precision engineering applications.

Hexagonal Head Shoulder Bolts are often used in applications like automotive components, manufacturing equipment, and machinery. They help guide or align moving parts, support pivot points, or securely hold parts at a specific distance. Their durability, precision, and ease of installation make them a versatile choice for mechanical assemblies that require robust and reliable fasteners.
