ASME B 18.5 T- Head Bolts
ASME B18.5 T-Head Bolts are inch-series fasteners featuring a T-shaped head designed to provide a secure bearing surface and convenient installation in machine fixtures, tooling systems, equipment assemblies, and other industrial applications. The T-shaped head allows the bolt to engage with a corresponding slot, channel, or mounting structure, while the threaded shank is secured with a nut to provide a reliable and adjustable fastening connection.
Manufactured according to the dimensional requirements of ASME B18.5, our T-head bolts are available in carbon steel, alloy steel, and stainless steel for different strength and environmental requirements. Mechanical grades can be supplied according to applicable specifications such as SAE J429 for carbon and alloy steel, while stainless steel options can be manufactured to ASTM F593 requirements. Standard and custom sizes, thread specifications, lengths, materials, and surface finishes are available according to customer drawings and application requirements.
Specification:
ASME B18.5 T-Head Bolts are manufactured to the dimensional requirements of ASME B18.5 and are available in different materials, thread specifications, mechanical grades, and surface finishes to meet a wide range of industrial applications. The standard defines the basic dimensions and configurations of the bolts, while applicable material and mechanical property standards are selected according to the required strength and service environment.
For carbon and alloy steel T-head bolts, SAE J429 grades such as Grade 2, Grade 5, and Grade 8 can be specified for different strength requirements. For stainless steel applications, ASTM F593 provides the applicable material and mechanical requirements for stainless steel fasteners, including commonly used ss304 t-bolts and 316 t-bolts . Thread requirements are generally based on ASME B1.1, while surface finishes such as zinc plating, hot-dip galvanizing, and stainless steel passivation can be supplied according to the applicable finishing standards.

Application of ASME B 18.5 T- Head Bolts:
ASME B18.5 T-Head Bolts are used in applications where a T-shaped head provides a convenient and secure connection with a slot, channel, fixture, or mounting structure. Their compact head design allows the bolt to be positioned and tightened in confined or slotted assemblies, making them suitable for industrial equipment, machine fixtures, tooling systems, and various mechanical assemblies. Material, strength grade, size, and surface finish can be selected according to the operating environment and fastening requirements.
Machine Fixtures & Tooling Systems
T-head bolts are commonly used for securing machine fixtures, workholding devices, jigs, tooling plates, and other components used in manufacturing equipment. The T-shaped head can engage with a corresponding T-slot or mounting channel, allowing components to be positioned and securely clamped. They are suitable for machining equipment, production lines, assembly fixtures, and other applications requiring adjustable positioning and reliable fastening.
Industrial Equipment & Mechanical Assemblies
ASME B18.5 T-head bolts are also used in industrial machinery, equipment frames, mounting systems, agricultural equipment, conveyors, and mechanical assemblies. Different thread diameters, lengths, materials, and mechanical grades can be selected according to the required clamping force and installation conditions. Carbon and alloy steel options can be supplied to applicable SAE J429 grades for different strength requirements.
Stainless Steel & Corrosive Environments
Stainless steel T-head bolts are suitable for applications where improved corrosion resistance is required, including food processing equipment, outdoor machinery, marine equipment, chemical processing systems, and other demanding environments. Stainless steel options can be manufactured according to ASTM F593 requirements, with 304 and 316 stainless steel available for different levels of corrosion resistance. Plain, passivated, and other suitable finishes can be supplied according to the application.
