This 4.0 x 25mm blind rivet is manufactured to DIN 7337 in A2 stainless steel (304 grade). DIN 7337 specifies a dome head rivet set by pulling a mandrel through the body, for fixing where only one side is accessible. Pulling the mandrel expands the rivet body against the blind face and snaps the stem off, producing a permanent fixing with no access to the reverse of the joint.

Typical applications

Fixings where the reverse side is closed or inaccessible
Sheet metal, cladding, and panel assembly
Ducting, signage, and enclosure work
Vehicle body and trailer repair

Available in packs of 25 to 200, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns. For coastal, marine, or chloride-rich environments, Simfix A4 (316 grade) equivalents are available.

RRP: £10.71

How do I choose between A2 and A4 stainless steel?

A2 (304) stainless steel suits most indoor, outdoor and workshop jobs. Choose A4 (316) marine grade for coastal, marine, poolside or other chloride-rich environments.

How do I make sure I order the right size?

Check the size in the product title and the standard, material and dimensions in the Product Specification tab. In M8 x 30, M8 is the thread diameter and 30 is the length in millimetres. See our size guide if you need more help.

When will my order arrive?

Orders placed before 3:30pm Monday-Friday are typically dispatched the same working day and every order is tracked. Next-day delivery is free over £50, or £5.50 below that threshold. Full options are shown at checkout.
