What Are Automotive Push-Type Retainers Used For?

Typical applications, the industries that specify automotive push-type retainers, and how to choose the right size, material and finish for the joint.

Automotive Push-Type Retainers are used for permanent, vibration-proof joints in sheet and plate. They are manufactured to Trade series (automotive push-type retainers), and selection is driven by the nominal diameter, the fit and tolerance the assembly requires, and the service environment.

Application guide for Automotive Push-Type Retainers to Trade series (automotive push-type retainers). The core duty of the type is permanent, vibration-proof joints in sheet and plate. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below.

Typical Applications for Automotive Push-Type Retainers

The most common settings where these are specified:

  • 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.
  • Sheet-metal assembly: permanent joints in ductwork, panels and enclosures.
  • Bodywork & trailers: blind joints where only one side is accessible.
  • Signage & cladding: fast, vibration-resistant fixing of thin panels.

How to Specify Automotive Push-Type Retainers 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 (automotive push-type retainers). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

Installation & Assembly Practice

  • Drill the hole 0.1 mm over the nominal rivet diameter and deburr both sides before setting.
  • Grip range must match the total joint thickness — a rivet set outside its grip range clamps poorly and works loose.

Common Selection Mistakes with Automotive Push-Type Retainers

  • Setting a rivet outside its grip range, which leaves the joint loose from day one.
  • Using aluminum rivets on steel sheet outdoors — galvanic corrosion eats the rivet.

Where Automotive Push-Type Retainers Are Not the Right Choice

Not where the joint must later be disassembled, and not for high-tension structural connections.

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.

Frequently Asked Questions

Which industries use Automotive Push-Type Retainers?

They are commonly specified in sheet-metal assembly, bodywork & trailers and signage & cladding, among other sectors.

How do I choose the right size of Automotive Push-Type Retainers?

Match the size to the mating part using the dimension table on this page.

Can Automotive Push-Type Retainers joints be taken apart?

No — rivets form a permanent joint and must be drilled out to remove. Use a bolt or screw where you need to disassemble the joint later.

What material should Automotive Push-Type Retainers be for outdoor use?

For damp, coastal or chemical environments specify A4 (316) stainless or a suitably coated steel. For indoor or dry use, A2 (304) stainless or zinc-plated steel is normally adequate.

Can I get a quote for Automotive Push-Type Retainers in the size and material I need?

Yes. Use the technical drawing and quote form on this page to set the size and options, then send the exact configuration to our team for pricing and lead time.
