Assorted Bolts

A Bolt is a type of fastener consisting of a threaded pin or rod with a head at one end, designed to be inserted through holes in assembled parts and secured by a mated nut that is tightened by applying torque.


  • Carriage bolts: Carriage bolts feature a domed or countersunk head with a square underside that prevents turning post-installation. They are often used with wood and masonry.
  • Flange bolts: Flange bolts are a specialized type of hex head bolt that has an integrated flange that serves as a washer component to more evenly distribute the load.
  • Plow bolts: Similar to carriage bolts, some plow bolts have a square-shaped countersunk top. Others have a domed design. These bolts are ideal for heavy-duty applications like industrial machinery.
  • Hex head bolts/ Hex Head Cap Screw: Characterized by their hexagonal head shape, hex head bolts are a broader category of bolts that requires installation with a wrench. They are available in many lengths and threading varieties. Hex Head Cap Screws have tighter tolerances and are the most common Hex Bolt category.
  • Square head bolts: Like hex head bolts, square head bolts are defined by their head shape—i.e., square. This head design facilitates tooling gripping, allowing for easier installation.
  • Socket Head Cap Screws/ Allen bolt: Socket head cap screws have a flat chamfered top surface with a smooth or knurled cylindrical sides. Forged heat-treated alloy examples are high strength fasteners intended for the most demanding mechanical applications, with special alloy formulations.
  • Additional bolt types: The other bolt types that we can custom manufacture include anchor, belt (e.g., eye, hook, J, and U), countersunk, lag, and T-handle bolts.
