Sealey AK3984 Short-Arm Threaded Nut Riveter

Rivetter, sealey, short arm, threaded nut insert.jpg

Ever wondered how you could fasten a bolt into a piece of metal when you can't get to a nut on the other side? The Sealey short arm threaded nut riveter of course!

It's a pain when you can't access the other side, right? So, this tool fits a threaded insert into a pre drilled hole, and then compresses it to provide a firm fixing for the bolt.

What's in the box? Unfortunately, no “nutserts", but they are easy to get from motor factors or online suppliers. Included though is:-

One short arm riveter,

A spanner to fit the mandrels,

Rivet mandrels in sizes,

M3 x 0.5

M4 x 0.7

M5 x 0.8

M6 x 1

M8 x 1.25

This is capable of being used with aluminium, steel, and stainless steel nutserts.

The mandrels are in handy boxes, labelled to remind you what size they are, but it's stamped on them anyway! They are easy to change, for use with different thread sizes, and a spanner is included for this very purpose. There's a knack to changing the mandrel, you have to remove the hexagonal part, then press the tube down to remove the mandrel itself. Seriously, it's easier to do than explain!

In use, having chosen the size of nutsert you want, and drilled the right sized hole, you have to adjust the length of stroke to compress the nutsert to grip the sheet metal. Once set, you put the nutsert on the mandrel, push it into the hole, and pull the arms together. All very simple. Very quick, accurate and easy. Too much pressure can strip the threads either in the nutsert, or on the mandrel, which is a consumable part. Just be careful with the smaller sizes. Practice setting them in a similar thickness of metal before you go for it on your important job! I’ve used them for several tasks on the Landy, and they have performed well every time. I put a smear of copperslip on the bolts being fitted too, but to be fair, I do that every time with every bolt.

The riveter was £37.95 from Amazon, and a box of 100 assorted nutserts will cost about a Tenner. I know, it’s a bit of an expense I suppose, but I have had a lot of use from it already. (I wondered about including a joke about short arm inspections... But thought better of it. Oh. Hang on.... :))
