Metric Bolts
AALL AMERICAN Fasteners offers a wide variety of quality metric bolts suitable for all applications.

Metric bolts are externally threaded devices used in conjunction with similarly threaded metric nuts or tapped holes to join two or more components.  Metric bolts are available in a variety of sizes, strengths, materials and finishes and are an integral part of a mechanical joint.

When designing a mechanical joint, it is important to ensure the bolt, nut and material being joined are compatible in thread dimension, material and finish to guard against galling, joint weakness or failure.  The method of installation, by hand tool or by high-speed machine, is also a key factor of joint integrity.  Ensuring the bolt grade and finish are suitable for the application and installation method is essential to a successful joint.

The characteristics of a bolt include the strength or class, the length, the diameter, the thread pitch and the material and finish.  Bolts may have a hexagon shaped head, a square head, a T-head or a slotted head requiring different tools for installation.
