ASME/ANSI B18.5 T-Head Bolts

ASME/ANSI B18.5 T-Head Bolts feature a distinctive T-shaped head that helps keep the bolt securely positioned during assembly and tightening. The head provides a broad bearing surface against the mating component, while its geometry can help prevent the bolt from rotating when a nut is tightened from the opposite side. This can be useful where access to the bolt head is limited or where maintaining a fixed bolt orientation is important during assembly.

The T-shaped configuration is particularly suitable for specialized fixtures, equipment frames, mounting systems, machinery components, and structural assemblies that require positive bolt positioning. The bolts can be selected by nominal diameter, length, thread series, head dimensions, material, strength grade, and surface finish to match the connection requirements and installation environment.

Specification of ASME/ANSI B18.5 T- Head Bolts:

ASME/ANSI B18.5 defines the dimensional requirements for T-Head Bolts, including the nominal diameter, length, head dimensions, and thread characteristics. The T-shaped head provides a defined bearing surface and helps retain the bolt in position during assembly, while the selected material and mechanical grade determine its suitability for different load and service conditions.

For carbon and alloy steel versions, SAE J429 Grade 2, Grade 5, and Grade 8 can be supplied where applicable. Stainless steel versions can be specified according to the applicable stainless steel fastener requirements, providing an option for applications where corrosion resistance is more important than maximum mechanical strength.
