What Are T-Bolt Hose Clamps Used For?

Typical applications, the industries that specify t-bolt hose clamps, and how to choose the right size, material and finish for the joint.

T-Bolt Hose Clamps are used for closing a hose, pipe or duct joint by band tension, selected by clamp range rather than by thread size. They are manufactured to Trade series (T-bolt hose clamps), and selection is driven by the nominal size, the fit and tolerance the assembly requires, and the service environment.

T-Bolt Hose Clamps are selected when an assembly calls for closing a hose, pipe or duct joint by band tension, selected by clamp range rather than by thread size. This application guide to the Trade series (T-bolt hose clamps) type covers concrete end-uses, the specification checklist, correct installation, and where an alternative fastener performs better.

Typical Applications for T-Bolt Hose Clamps

The most common settings where these are specified:

  • General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
  • Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
  • Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.

How to Specify T-Bolt Hose Clamps for Your Application

  • Size: Match the size to the mating part — see the dimension table below for each option.
  • Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
  • Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
  • Standard: This product is supplied to Trade series (T-bolt hose clamps). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Where T-Bolt Hose Clamps Are Not the Right Choice

Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.

Technical Drawing

Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.

  1. Wire rod feeding into a cold heading machine
    01

    Cold heading

    Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.

    Head dimensions and under-head radius checked at set-up and per shift.

  2. Thread rolling machine producing bolt threads
    02

    Thread rolling

    Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.

    Go / no-go ring gauges to ISO 965 tolerance class 6g.

  3. Baskets of bolts staged for heat treatment
    03

    Heat treatment

    Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.

    Core hardness and tensile tested per lot to ISO 898-1.

  4. Zinc plated bolts in a treatment basket
    04

    Surface treatment

    Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.

    Coating thickness and neutral salt spray hours to ISO 9227.
