A2 (304) Stainless Steel Clout (Slate) Nails, Standard and Wide Head
Mechanical properties, corrosion behaviour and the full dimensional range for this grade.
A2 Stainless Steel Clout (Slate) Nails, Standard and Wide Head are supplied to ISO 3506 group A2 (304 / 1.4301), commonly supplied A2-70. Corrosion behaviour is good general corrosion resistance, the material is largely non-magnetic, and the usable service range is approx. -200 °C to +400 °C, subject to the property class and the joint. In practice this grade is the most common stainless group for indoor and general outdoor fasteners.

Hidden Deck Fasteners Sourcing: Manufacturing, Types & Material Compatibility
A2 Stainless Steel is not a material clout (slate) nails, standard and wide head are supplied in. Clout (Slate) Nails, Standard and Wide Head are specified by nominal diameter, and this combination does not describe a part that exists.
A2 Stainless Steel is one of the grades the catalog describes. Dimensions, material, finish and form are specified from the drawing — a nail outside the standard range is a variation on existing tooling rather than a new design.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
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.

Materials & Grades
Select a material class to see the grades we supply it in. Each designation is listed with its ISO/EN, AISI/SAE, JIS and GB equivalents.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
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.
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.
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.
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 corrosion resistance do A2 Stainless Steel Clout (Slate) Nails, Standard and Wide Head offer?
A2 Stainless Steel Clout (Slate) Nails, Standard and Wide Head provide good general corrosion resistance with a service range of approx. -200 °C to +400 °C, subject to the property class and the joint.
Should I choose A2 Stainless Steel or A4 (316) for Clout (Slate) Nails, Standard and Wide Head?
For Clout (Slate) Nails, Standard and Wide Head, A2 Stainless Steel suits general indoor and outdoor use; A4 (316) is preferred for marine, coastal and chemical environments. Choose by corrosion exposure first.
Can A2 Stainless Steel Clout (Slate) Nails, Standard and Wide Head gall during installation?
Yes — stainless on stainless is prone to thread galling under load, especially at smaller sizes. Use an anti-galling lubricant or wax thread compound, and slow the tightening rate where possible.
Is A2 Stainless Steel food-grade?
A2 (304) is widely accepted for food contact in non-chloride environments; A4 (316) is preferred where chlorides are present.
