## Need chemical anchor studs (resin-bonded) in a size this table does not list?

This page covers M8 chemical anchor studs (resin-bonded). Embedment depth, thread size, body length and corrosion protection are the variables; capacity remains a concrete design value, not a property of the anchor alone. Made by hot forging or thread rolling.

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

## Applications & Industries for M8 Chemical Anchor Studs

Where Chemical Anchor Studs are used, and what decides the specification in each case. Stocked from M8 to M24.

### Industries that specify Chemical Anchor Studs

- **Close-to-edge fixings:** Anchors near a slab edge or at tight spacing.
- **Rebar & retrofit connections:** Starter bars and post-installed reinforcement.
- **Hollow block & masonry:** Resin with a sleeve where expansion would break the block.
- **Construction & structural:** Base plates, brackets and steelwork fixed to concrete.
- **Building services:** Suspending tray, duct, pipe and sprinkler runs from a soffit.
- **Plant installation:** Machines and equipment held down to a concrete floor.

### Typical applications

- bonded fixings with no expansion force in the substrate
- hole cleaning is most of the installation quality
- cure time roughly halves for every 10 °C above 20 °C
- making a load-bearing threaded fixing in concrete or masonry
- fixing a steel fixture through to a solid substrate
- suspended services on threaded rod

### 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.
- **Sealed joints:** Used where the fixing has to keep water or air out as well as hold — the elastomer, not the fastener, decides service life.
- **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.
- **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.

### Where to use something else

- Not for a substrate the type is not qualified in — an expansion anchor near an edge or in hollow block will split it.

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.

## Frequently Asked Questions

### What is the coarse-thread pitch of M8 for Chemical Anchor Studs (Resin-Bonded)?

For M8 the standard coarse pitch is 1.25 mm — this is the value used for Chemical Anchor Studs (Resin-Bonded).

### What clearance and tapping drill suit M8?

Use a 9 mm clearance hole (ISO 273 medium) for through-fixing, or a 6.75 mm tapping drill for a coarse M8 thread.
