Applications & Industries

The sectors that buy Huck C6L Small-Diameter Lockbolt Assembly to BS 7805 Part 1:1997, and the duty each one buys them for. Stocked from 4.8 to 9.5 (nominal diameter).

Industries that specify Huck C6L Small-Diameter Lockbolt Assembly

  • Rail interiors Vibration-exposed brackets and interior structures assembled from one accessible side.
  • Bus manufacturing Light structural joints where the collar is swaged after the pin is inserted.
  • Sheet-metal production Repeatable pin-and-collar installation where the rear face cannot be held.
  • Trailer bodies Small-diameter permanent joints in side rails, floor members and formed panels.
  • Transport & bodywork Trailer, bus and van panels joined blind from one side.
  • Signage & cladding Fast, vibration-resistant fixing of thin material.

Typical applications

  • choosing brazier, truss or countersunk pin head geometry for the panel face
  • matching collar style and grip to the combined material thickness
  • installing a lockbolt where vibration would work a removable nut loose
  • creating a permanent small-diameter pin-and-collar joint
  • permanent joints in thin sheet where a threaded fastener would loosen
  • blind fixing where only one side can be reached

Service conditions to specify against

Marine and coastal
Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
Vibration
Specified where cyclic load would loosen a plain nut or screw — rotating plant, rail, mobile equipment and anything that is not re-torqued in service.

Where to use something else

  • Do not specify this permanent assembly where routine removal is part of the service plan.
  • Not for a joint that has to come apart in service — removal means drilling the rivet out.

What Are Huck C6L Small-Diameter Lockbolt Assembly?

Huck C6L Small-Diameter Lockbolt Assembly are rivets defined by BS 7805 Part 1:1997. They are selected by nominal diameter and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.

Materials & Finishes

Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.

Pricing

Huck C6L Small-Diameter Lockbolt Assembly are supplied to order. Pricing starts from approximately US$1.50 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

Inside the plant

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.
