Rivnut/Nutsert Tool

[numpty]

As the title suggests, I'm looking at purchasing one of these.

There are kits available at reasonable prices on ebay, but are these "reasonable" quality, or can anyone suggest a good home workshop brand.

I need/want at least the capability of 8mm size for steel.

Hi Perry

Use the search function. There are a number of threads on here about Rivnut's & tools.

urmmm...
8mm hole to fit a riv nut to (which gives you about an m5 bolt)
you want to fit M8 bolts (which need about a 12-15mm hole)
OR you want to riv nut into steel 8mm thick? (in which case why, drill and tap the bugger)

What are you aiming to support? panel work, shelving? seats? what thickness?

How many do you need to set?

If your going to set the heavy wall inserts, ones for heavy duty restraining you need to get the ratcheting type slow going but hard to beat for the quality of the setting

(thats the old school non ratcheting version)

if you're only going into panel work and only need to set the thin wall ones the ones that work like a hand riveter are magic if you only do the light weight stuff but you'll mis set a lot of serts if you try to use them for the heavy stuff.

and the airserter....

Gosh Dave, but no, 8mm thread size ;) for fixing bits and pieces to sheet metal.

got mine from aerobolt Bolts & Huck Fasteners Sydney, Rivets, Nutserts & Sealants (http://aerobolt.com.au/) little pricey but very good quality, italian make from memeory but can not remember the make off top of my head.

ok so light stuff into sheet metal.

the thin wall ones will collapse reasonably well with the rivet action setter.

If you have the room make up an aligning/spacer block for the bottom handle so that when you rest the end of the handle on the block the inset screw in the head of the crimper is perpendicular to the panel. This will save you many miss-set nutserts.

I bought one of the cheapies on ebay and damned if I can get enough strength into the tool to upset the larger steel rivnuts, but it works a treat on the alloy rivnuts. I have only used up to M6 alloys though so far.

I just got a POP PNT210M from Bay fastening in the US $236 delivered .
good quality , effortless to use.
Very happy with it , glad I didn't get a cheapy .

[Davehoos]

last boss had one of these style from blackwoods in a wooden box.
we often did 10mm threads.
the steel spline lock nutserts you need something better.
good idea to buy a few replacement tips.

I bought a wurth kit that does m5 to m12. Fantastic gear and I'm probably down to $20 per hole now.

An alternative to using Rivenuts are nut plates. They come in all shapes and sizes. Aircraft Nut Plates | eBay (http://www.ebay.com/bhp/aircraft-nut-plates)

In my younger days as an electrical apprentice I did my fair share of switchboard (industrial) manufacturing. Rivenuts were used extensively and even with good quality tools didn't always set properly, and a real pain to replace.

Now that I'm building a metal airplane I've discovered the world of nut plates.:D

Never seen them before Ron.
How do you use them??? Looks like you pop rivet them in place.
Cheers

Hi Andrew,

Yes, you can use pop rivets, although for most aircraft applications solid rivets are used.

In this thread In need of Nutplate 101 - VAF Forums (http://www.vansairforce.com/community/showthread.php't=57848) there are some pictures of nut plates being used and some hand tools to help with the holding of the nut plate while your riveting them in. The tools make the job easier but not really required.

This chart covers the common types: http://www.gen-aircraft-hardware.com/images/pdf/nutplates.pdf

Not normally found in the aircraft aisle at Bunnings...:p Aircraft Spruce have a good range of hardware. Anchor Nuts from Aircraft Spruce (http://www.aircraftspruce.com/categories/aircraft_parts/ap/menus/ha/nut_anchor.html)

Speaking of which, I need to rivet quite a few to my wing spars, will be used to attach the fuel tanks to the wing...:eek:

I've often used similar practice in the past, ie make a plate to go behind/inside with tapped holes and pop rivet in place and may use this method again. Nutserts are so convenient though.

I got a Memfast tool from the said company in the UK. It is small so I can get in most places, and easy to use. It does up to M10 stainless and available with imperial mandrels. For just under 100 quid it to me seems reasonable quality.:D

[R Miller]

there is a cheap way to put in riv nuts aswell, use a bolt that matches the thread in the rivnut, and 2 washers, and a nut the next size up,

place one washer over the bolt, then the nut the next size up, then the washer, stick it into the hole u have drilled ( need to drill the hole perfect ) then use the nut to keep the rivnut square to the panel and tighten up the bolt,

I worked for a truck building company and we had to share one nutsert gun around the factory, so we just did it our own way most the time

Another alternative for smaller sized nutserts:

Dafra Rivnut Adapter for cordless drill. www.dafra.com.au - YouTube

Attaches to a drill and is available at: Rivets Rivnuts & Tooling - Dafra - Melbourne (03) 9555 6872 (http://www.dafra.com.au/default.html)

For small fasteners you can get threaded pop rivets. King Klik and Marston both used to list them. They used to go up to No.10 - 3/16". Very convenient for sheet metal work up to 16 gauge. A steel threaded mandrel is screwed into the threaded rivet and the rivet set by normal means. The mandrel is then unscrewed and you have a thread ready to accept a fastener.

I do SAAA S C of A's and am a LAME


we call them anchor nuts, but the yanks like to change english so they can call it their own.

Hi Harry,

I'm building a Vans RV 7A and am a member of SAAA Chapter 24. Next weekend there is the state fly in to Denmark airport hosted by Ch13 (the Albany guys).

I got one like this (http://www.ebay.com/itm/Rivet-Nut-Tool-Kit-/131055518884), although not from this mob. I haven't used it yet, but it can be driven with a cordless drill.
