About this fitting
This is a fitting in Carbon Steel, at strength class Grade 4.8, supplied blue zinc plated, with an 3 thread. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
General-purpose hardware that completes a fastening job rather than carrying the load itself. Used in furniture, rigging, cable management and general assembly work alongside the fasteners on this store.
Carbon steel is the workhorse material for structural fastening. Grade 8.8 and above must be coated (zinc, black oxide or Dacromet) or it will rust outdoors.
Grade 4.8 is low-carbon steel at 400 MPa tensile / 320 MPa yield. Suitable for light-duty, non-critical joints and the cheapest option per piece.
Is this not quite the size or grade you need? Ask us — we produce small batches to drawing and to DIN, ISO, GB and JIS standards, and we consolidate pallet and container loads for trade orders.
