Carriage Bolts

Description

Carriage bolts, commonly known as round-head square-neck bolts, are fasteners with a round or semi-circular head and a square neck. They are used with a nut to connect parts with through holes.

Carriage bolts are classified by head size into large semi-circular head carriage bolts and small semi-circular head carriage bolts, and are widely used in electronics manufacturing, machinery equipment, chemical industry, automotive industry, and many other fields.

Carriage Bolt Standards:

The Chinese standard system includes GB/T12 (small semi-circular head) and GB/T14 (large semi-circular head), corresponding to different head sizes. The German DIN603 standard defines the technical parameters of large semi-circular head square-neck bolts. American standards conform to ASME/ANSI B18.5-2008, with diameter markings using imperial units.

Carriage bolts are mainly made of carbon steel and stainless steel, and surface treatments include galvanizing and blackening. The product diameter typically ranges from 5mm to 20mm, and the highest mechanical performance grade is 12.9.

Features of Carriage Bolts:

The head features a round or semi-round design with a square neck at the bottom to prevent rotation during installation.
The shank has external threads that mate with a nut for tightening. Thread types include metric coarse, fine, and imperial.
The new patented product utilizes a combination of a rubber cushioning layer and a hardener inside the fiberglass shell to strengthen the connection structure.
