## Applications & Industries

Heavy-Duty Roofing Insulation Fasteners are bought for a small number of well-defined jobs. These are the ones we ship them for. Stocked from coated self-drilling screw to coated screw for concrete (nominal diameter).

### Industries that specify Heavy-Duty Roofing Insulation Fasteners

- **Building envelope:** Uplift-designed fastening patterns.
- **Flat roofing:** Insulation boards against wind uplift.
- **Commercial construction:** Steel, timber and concrete decks.
- **Roof refurbishment:** Over-boarding existing decks.
- **Fit-out & drylining:** Fixings into board, block and hollow wall.
- **Construction & structural:** Base plates, brackets and steelwork fixed to concrete.

### Typical applications

- checking fastener embedment into the deck
- taking the plate diameter and pattern from the uplift calculation
- matching the fastener to the deck material
- setting the plate flush without dishing the board
- making a load-bearing threaded fixing in concrete or masonry
- fixing a steel fixture through to a solid substrate

### 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.
- **Hole preparation:** Drilled diameter, depth and cleanliness are part of the specification; an uncleaned hole is the single most common cause of a failed anchor.
- **The concrete governs:** Capacity is a property of the base material and the geometry — grade, edge distance, spacing and cracked or uncracked — not of the anchor alone. Work to the anchor manufacturer's ETA or ICC-ES report.

### Where to use something else

- Do not set the fastening pattern by board size; wind uplift is the design case and it varies across the roof.
- Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.

Heavy-Duty Roofing Insulation Fasteners (Trade series (roof insulation fasteners and plates)) are a type of anchors & concrete fixings used across industrial assembly. Below is the complete size table together with material, standard and application guidance.

## What Are Heavy-Duty Roofing Insulation Fasteners?

Heavy-Duty Roofing Insulation Fasteners are anchors & concrete fixings defined by Trade series (roof insulation fasteners and plates). 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.

## Specification Guides

Each size, material and standard of Heavy-Duty Roofing Insulation Fasteners has its own reference page with the figures for that one configuration.

## Goes With

Hardware commonly specified alongside Heavy-Duty Roofing Insulation Fasteners.

## Pricing

Heavy-Duty Roofing Insulation Fasteners are supplied to order. Pricing starts from approximately US$0.14 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.

Custom manufacturing · Made to drawing

## Need a heavy-duty roofing insulation fasteners outside the standard range?

Length and corrosion protection are the usual specials. The load a fixing will take is decided by the concrete and the edge distance, not by ordering a longer anchor. Made by hot forging or thread rolling.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

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](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 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](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 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.
