Trade glossary

Every trade runs on shorthand. A specification says “S3 SRC minimum, cut level 5, 8.8 BZP, imprest replenished weekly” and assumes you already know what all of that means. This glossary explains the shorthand - and, more usefully, tells you what each term means when you are the one placing the order. Every entry carries a buying note: the practical bit, the catch, or the thing that most often goes wrong.

Procurement & compliance

The language of PQQs, approved-supplier lists, site paperwork and stock arrangements. The section to read if you are the one being asked for evidence.

46 terms

PPE & safety standards

Hi-vis classes, footwear ratings, glove codes, helmet types, respiratory and height standards - what each marking means and where specifications go wrong.

52 terms

Fixings, fasteners & threads

Property classes, DIN numbers, stainless grades, coatings, thread forms and anchors - the detail that decides whether a fixing lasts.

42 terms

Tools, abrasives & consumables

Drill shanks and bit materials, abrasive disc types, socket drives, insulated tools and the chemicals that go with them.

30 terms

Every term, A–Z

170 terms across four sections. The tag after each entry says which section it sits in. Terms marked guide have a page of their own rather than a glossary entry, because they come up often enough on specifications and pre-qualification questionnaires to be worth several hundred words rather than fifty.
