16 Pcs Porcelain Lamp Holder Socket E26/E27 Medium Keyless Threaded Socket with Two Hole Flanged Mounting 660W 250V Medium Base Lampholder Cleat Sockets for Indoor Garage Closet Lighting

Perfectly good holders. I use it for 3d printing projects and they work quite nicely. 5mm screws fit the holes, so that is what i used to attach it to a 3d printed base. The porcelain makes the wholes not 100% consistent, but you can file them to make them fit better. They add nice weight, which is also nice for my purposes. So far no complaints.

Good product

well manufactured product. This opinion is coming from a tooling engineer. I would buy again if the need arises.. - Neil Ward.

Saysurey 4 Pcs Porcelain Lamp Holder Socket E26: . There are some very tiny fractures on the bottom of these sockets in the porcelain. Shrink fractures likely when baking. Probably ok but time will tell. . These should be installed in an enclosure since the electrical wires are exposed where attached.

Easy to wire and fast

I wish this had instructions included, but It’s self explanatory if you know a little bit about how to wire things. Installation may be easy for some but others may need to hire help. The quality seems good but be careful because porcelain will break if it falls so handle with care. The item has all the parts visible and easily accessible to install the wiring. It comes with 8 sockets so this is excellent for projects. I recommend getting an electrician or watching a DIY tutorial first if your not familiar with how to install electrical wiring.

Ordered two packs of these sockets. Used all 16 and none had any problems. Sturdy terminals and very easy side connection for DIY projects.

So much better than the plastic versions
