Serrated Patches and Washers
Serrated pads and washers are used to provide adjustment for a vertical / horizontal fixing.
- Brickwork fixings
- Stonework fixings
- Solar shading fixings
- Timber engineering
- Façade engineering
- Secondary steelwork
Serrated pads and washers are suitable for applications where -
- A vertical fixing requires vertical adjustment during fitting and levelling
- A horizontal fixings that requires horizontal positional adjustment during fitting.
When the correct position is achieved the bolt fixing must be tightened to the appropriate torque value. The fixing is then locked into position.
Serrated pads and washers are available in carbon steel and stainless steel.
|Carbon Steel||Grade S275||Grade S355|
|Stainless Steel||Grade 304/1.4301||Grade 304L/1.4307|
|Stainless Steel||Grade 316/1.4401||Grade 316/1.4404|
Our serrations are machined to a standard 3mm pitch (rather than pressed or stamped).
This produces clean, sharp and accurate fit for our patches and washers.
We hold stock of our standard sized serrated pads and serrated washers.
|Standard Pad||40mm wide||80mm Long|
|Standard Washer||40mm wide||40mm long|
|Slots - 60mm long||14mm wide (M12)||18mm wide (M16)|
|Holes||14mm (M12)||18mm (M16)|
We can manufacture bespoke sizes of pads and washers depending on your requirements - speak to your sales contact.
Bespoke hole sizes or slot sizes can be cut depending on your requirements - please talk to your sales contact.
Carbon steel serrated pads and washers can be galvanised. For more information see galvanising
‘Note’- where the patches have been welded to a main fabrication the zinc coating may require heating and cleaning after galvanizing to ensure that the serrations are free to interlock.
The amount of cleaning will depend on the orientation of the fabrication during galvanizing and how the piece was withdrawn from the gavanising bath.
Serrrated washers should be ‘Spun Galvanised’ for best results. We can offer further advice based on our experience. Please talk to your sales contact.
You can buy standard components from our online SHOP. Or call our sales desk for your requirements.
Stainless steel or mild steel patches and washers. Suitable for welding to angle brackets and providing adjustment for stone cladding supports, balcony structures and external brickwork support.
