T Head Bolts

T Head Bolts are versatile fastening components designed for applications where a secure connection and flexible positioning are required. Their T-shaped heads allow the bolts to engage with slots, channels, and other specially designed mounting systems, making them convenient for assembly and adjustment without requiring additional drilling or modification. They are widely used in aluminum extrusion structures, machinery and equipment, conveyor systems, fabrication projects, and other modular assemblies.

We manufacture T Head Bolts in a wide range of sizes, materials, strength grades, and surface finishes to meet different application requirements. Stainless steel options such as 304 and 316 provide good corrosion resistance for demanding environments, while carbon steel options are available for applications requiring higher strength or cost-effective fastening. Different thread sizes, bolt lengths, and head configurations can be supplied, with customized T Head Bolts available according to customer drawings, samples, or specific assembly requirements.

Dimension Standard:

Our T Head Bolts are available in both metric and inch dimensions to meet different aluminum profile, T-slot, and industrial fastening requirements. The dimensional specifications vary between the two systems according to their intended applications and applicable standards. Metric T Head Bolts are primarily designed for European-style aluminum extrusion profiles, with dimensions selected to match common T-slot profile systems. Inch T Head Bolts are manufactured according to the dimensional requirements of ASME B18.5 and are available in commonly used inch thread sizes and lengths.

Aluminum Profile T-Bolts

Aluminum Profile Metric T-Bolts

Metric T Head Bolts are commonly used with European-style aluminum extrusion profiles and T-slot framing systems. Their head dimensions are designed to fit the corresponding profile slot, allowing the bolt to slide into the aluminum extrusion and be positioned at the required location before tightening. Common metric thread sizes and dimensions are available for different aluminum profile series.

ASME B 18.5 T- Head Bolts

ASME B 18.5 T-Bolts

Inch T Head Bolts are manufactured according to the dimensional requirements of ASME B18.5. The inch-size dimension chart covers commonly used thread diameters, lengths, head dimensions, and other applicable dimensions. These T-head bolts are suitable for applications using inch-based fastening systems and can be supplied in different materials, strength grades, and surface finishes according to project requirements.

Mechanical Proeprty:

The mechanical properties of T Head Bolts depend on the material, strength grade, and applicable fastener standard. We supply T Head Bolts in carbon steel, alloy steel, and stainless steel, with mechanical properties specified according to applicable standards such as SAE J429, ISO 898-1, ISO 3506-1, ASTM F593, and ASTM A307. These standards define the required tensile strength, yield or proof strength, hardness, and other mechanical characteristics according to the selected material and grade.

For carbon and alloy steel T Head Bolts, commonly specified grades can be manufactured according to SAE J429 or ISO 898-1, depending on the required strength class and dimensional system. Carbon steel T Head Bolts for general-purpose applications can also be supplied to ASTM A307 Grade A where applicable. For stainless steel T Head Bolts, SS304 t-bolts and SS316 t-bolts options are available with applicable property classes under ISO 3506-1, while ASTM F593 can be used for stainless steel fasteners specified to ASTM requirements.
