Merriway BH02847 (20 Pcs) Hammer Type Solid Wall Fixing with Nylon Plug, M8 x 80mm (5/16 inch x 3.1/8 inch) - Pack of 20 Pieces

Don't know how we did before these were mainstream, so much quicker than measuring a separate hole. I predrill the timber with a wood bit then hold up and use the masonry bit into the wall and obv just hammer in without moving the wood. Also useful for very heavy applications where going to use thunder bolts as these will keep it in place so you've both hands free to put additional thunder bolts in where that is required. only a few pence each so don't mind "wasting" them on that too.

The Merriway M8 x 80mm long fixing plugs are a standard size incorporating suitable screws for medium loads. The thread profile allows hammer-in but not pull-out. The thread allows for unscrewing when required.I find it is best to gently tap the plastic plug through object being fastened and wall without the screw, and then tap in the screw partway and finish off with a suitable driver.As with all these types of fixing, one needs to be aware of the strength of the materials in the wall and the loading of what is being fixed to the wall to be able to safely select suitable positioning, size and number of fixing plugs.

They are solid concrete mounts but beware. These are advertised as hammer in fixings. I bought them to fix wooden studs into concrete wall. So idea is: you stick your wood against the wall. You drill through the wood and through the solid wall in one go (you mark the drill to the depth of the plug). You insert the plug and hammer it home. Simple? Or should be not with these. Every single time when I tried hammer them in they bent. WTF. I cursed a lot. Then I screwdriver them in instead of hammering in. Perfect! Strong good hold and straight plug. Tell me what did I do wrong in my fixing process with hammer so they bent? Maybe I just can’t do it, not sure. Either way 4/5 - would’ve been 5/5 if I actually could hammer them in easily instead of using Philips screwdriver.

Good size screws and plugs Great value for money

Screw head too soft will strip the hex and will not screw home had to use standard pz screws.

Have to be careful to drill correct size holes but if tightly fitting through wood and brick no problems. Hammered until firm and finished with screwdriver

Not much to say about these. I’ve used them on several jobs from hanging heavy mirrors to anchoring shelving and they’re still there! I live in a new build and use these when fixing into the block work. Only note is you often need a very long drill bit to get through void between plasterboard and brick.

These are great, depending on what you want from them.If you'll be driving the screw all the way into the plug then you're probably fine. I've mounded a large TV on the wall with 4 of these no problem!But when I tried to mount my standard Ikea bathroom cabinet, where the screw head needs to be stood off from the wall by 1.5/2cm the thread wouldn't bite as the screw (and plug) are only partially threaded. I ended up using the corefix screws which produced an infinitely better fixing!

Lo he utilizado para sujección de unos tableros de madera forrando el techo y funciona perfectamente. Todo muy correcto
