Sourced and supplied across Saudi Arabia
A bolt is not described until five things are stated, and enquiries routinely give two. Diameter and length are the easy ones. The property class is the one that matters most — under ISO 898-1 a class such as 8.8 or 10.9 encodes the tensile strength and the yield ratio, and substituting a lower class into a joint designed for a higher one is invisible on the shelf and structural once it is installed. Thread matters next: coarse and fine threads of the same nominal diameter are not interchangeable, and neither are metric and imperial threads that measure almost the same. Then the finish, which in this region is a corrosion decision rather than a cosmetic one, because plain black bolts on an external structure near the coast will bleed rust down the steelwork within a season. And say whether the nuts and washers are needed, because a matched set is what you actually install.
The more of this you send, the closer the first quotation lands.
| Property class | Such as 8.8 or 10.9 per ISO 898-1 — this is the one to state |
|---|---|
| Diameter and length | Nominal diameter and the length under the head |
| Thread | Coarse or fine, metric or imperial — they do not interchange |
| Thread length | Fully threaded or part threaded, and the plain shank required |
| Head type | Hexagon, socket cap, countersunk, or carriage |
| Finish | Plain, zinc plated, hot dip galvanised, or stainless |
| Corrosion exposure | Coastal or external structure — plain bolts will stain the steel |
| Nuts and washers | Matched class nuts and the washer type required |
| Certification | Material certificate type and any batch traceability required |
| Application | Structural connection, machinery, or general assembly |
| Temperature | State if the joint runs hot or is in a low temperature service |
| Quantity | Per size and class, with the annual usage if it repeats |
