T-bolts, also known as T-slot bolts or hammer bolts, are specially designed fasteners used to secure components to workpieces with T-slots, such as machine tools, fixtures, or other equipment. The design of this bolt allows for quick installation and removal, making it particularly useful in situations where frequent maintenance or replacement of parts is required.

T-bolts are made of stainless steel (such as SUS304), carbon steel, and alloy steel. Different materials are suitable for different applications, such as stainless steel for applications that require high corrosion resistance.

T-bolts come in sizes ranging from M8 to M64, covering a wide range of possible application requirements.

T-bolts are often used in conjunction with flange nuts for better fastening. This combination is a standard matching connector for installing angle fittings.
