Standards & Certification

Built to Australian spec.
Lab-tested to prove it.

Every product Crimps supplies is manufactured to the relevant AS/NZS or ISO standard. Every shipment arrives with a current test certificate from an independent, NATA-accredited laboratory — matched to the batch, not a generic mill report.

What We Supply Against

Same product. Same cert.
Shorter chain.

Structural fasteners are one of the most standardised product categories in construction. A Grade 8.8 hex bolt to AS 4291.1 is a Grade 8.8 hex bolt to AS 4291.1 — whoever makes it. The steel is specified. The test methods are specified. The performance is specified.

Crimps sources from manufacturers whose production is validated to these same Australian and international standards. The difference is that we supply direct — cutting out the importer, wholesaler, and reseller layers that add cost without adding compliance value.

When you tender for a structural job, you can hand your engineer the same compliance pack they'd get from a major distributor. Without the markup.

Key Standards We Supply Against

AS 1252 High strength structural bolt, nut and washer assemblies for structural steel
AS 4291.1 Mechanical properties of fasteners — bolts, screws and studs
AS 1111.1 ISO metric hexagon commercial bolts and screws — product grades A and B
AS 1112 ISO metric hexagon nuts — product grades A, B and C
AS/NZS 3566 Self-drilling screws for the building and construction industries
AS 5216 Design of post-installed and cast-in fastenings in concrete
ASME B16.5 Pipe flanges and flanged fittings — petrochemical stud bolt specification
NATA Accreditation

What a NATA cert actually means.

NATA (National Association of Testing Authorities) is Australia's peak body for laboratory accreditation. A NATA-accredited test certificate is engineer-acceptable, project-submittable, and the benchmark for structural compliance in Australia.

Batch-Matched Documentation

Every test certificate is matched to the specific batch delivered — traceable from your site back to the heat number and production run. Not a generic mill-wide document that may not reflect your actual product.

Independent Laboratory Testing

Testing is performed by an independent NATA-accredited laboratory — not the manufacturer's in-house quality team. Tests cover tensile strength, proof load, hardness, and coating thickness as applicable to the product standard.

Engineer-Acceptable Compliance

A current NATA-accredited certificate is the standard engineers, project managers, and certifiers expect when reviewing a structural fastener substitution. Supplied with every order — no extra request required.

Why It Matters

Compliance isn't the hard part.
Paying twice for it is.

If you already buy to Australian Standard, you already do the hard work. Crimps exists so you stop paying a premium for a compliance story that's been retold three times on the way to you.
