M8 x 20mm Flanged Hex Head Bolt (DIN 6921) | A4-70 Stainless Steel
This M8 x 20mm flanged hex head bolt in A4-70 Stainless Steel is commonly selected for securing machine guards, cover plates and service panels. Manufactured to DIN 6921, it uses a 18mm flange diameter and 13mm across flats to give a practical hex driven fixing for machinery guarding.
This one-piece flange design reduces loose hardware so the fastener can seat cleanly against flat or slotted components. Its 8.1mm head height and 18mm flange diameter should be checked against the available clearance before final selection.
Common Applications
- Machinery Guarding: securing machine guards, cover plates and service panels.
- Frame Assembly: helps spread clamp load around access points that may be removed during maintenance.
- Service Panels: creating a neat fixing for removable covers.
- General Engineering: standardising parts around the DIN 6921 format.
