Mechanical properties, corrosion behaviour and the full dimensional range for this grade.
A2 Stainless Steel Wire Rope Clip (U-Bolt) 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.

A2 Stainless Steel is not a material wire rope clip (u-bolt) are supplied in. Wire Rope Clip (U-Bolt) are specified by rope diameter, and this combination does not describe a part that exists.
Need this rigging hardware in a grade that is not listed?
A2 Stainless Steel is one of the grades the catalog describes. Dimensions, material, finish and form are specified from the drawing — a rigging hardware outside the standard range is a variation on existing tooling rather than a new design. Made by hot forging.
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
Can A2 Stainless Steel Wire Rope Clip (U-Bolt) — ISO / DIN (Series 157) be used with aluminum?
Yes, but stainless drives mild galvanic corrosion of aluminum in wet service — isolate with a coating, sleeve or paint, or accept the trade-off if the joint is dry and indoor.
What's the service temperature limit for A2 Stainless Steel?
The practical service range is approx. -200 °C to +400 °C, subject to the property class and the joint.
Can A2 Stainless Steel replace plated alloy steel structurally?
Only at the standard strength classes — A2-70 / A4-80 are roughly equivalent to class 7 steel; A4-100 reaches class 8.8. For class 10.9 or 12.9 strength, plated alloy steel is required.
Are A2 Stainless Steel Wire Rope Clip (U-Bolt) — ISO / DIN (Series 157) magnetic?
A2 Stainless Steel Wire Rope Clip (U-Bolt) — ISO / DIN (Series 157) are largely non-magnetic.
