Review: Good choice - It's worked
Review: Beautifully machined and accurate - I needed a strong wall anchor that I could easily remove later on, for a really damp location. That's a difficult combination, as it rules out steel (which rusts) and plastic (not strong enough). I used the same type of thing decades ago and was surprised to find someone still making them. They are beautifully machined and very accurately made. I used these with stainless bolts and they are excellent. Well able to take the weight of a bench seat and a barbecue table on a stone wall. With care, they are also able to be removed if needed. Very happy with these, as I'm sure you would be.

## Features

- DROP-IN-ANCHORS - Are female concrete anchors designed for anchoring into concrete. Drop the anchor into the pre-drilled hole in the concrete. Using a setting tool expands the anchor within the hole in the concrete. Drop-in anchors require a setting tool to install. Size of M4. Pack of 10.
- EASY INSTALL - Bullet type anchor shell with internal thread for pre-positioned installation. When the bullet is placed in shell & hit with a setting tools it slides forward & the inside part of shell expands and takes the grip in the wall.
- HEAVY DUTY - Brass anchors made of high-quality brass will not crack under impact at low temperatures. It is also suitable for attaching components to concrete and solid brick.
- ADVANTAGES - The reinforced walls of the anchor make it possible to achieve high loads while maintaining resistance to vibration. They protect the bonded-in part of the steel element from corrosion and aggressive chemicals. Bolts or studs can be remove and replaced without affecting the holding power.
- UNIVERSAL USE - Drop-In Anchors by Keple often used to support handrails, lightening fixtures, piping and more. ​Brass anchor fasteners in anchors are multifaceted and are able to work any surface like brick, concrete, metallic or timber based surfaces.

### ⭐ Absolute rubbish
*by J***Y on 25 May 2025*

Absolute rubbish, anchors are supposed to have a wedge at the bottom, to tap down with a drift ,pushing the bottom of the anchor wider to grip the concrete. These turned up with no wedge, the brass is of inferior quality and brittle. I'll be sending them straight back!
