7 mm x 50 mm Zinc-Plated Hex-Drive Connecting Screw (4-Piece per Pack)

Good for anchoring a wheelchair transition to a ramp

Makes for a nice finish look when lagging interior wood supports such as the barn door I installed. Put the door rail on a pine ledger so I could bolt to the existing stud spacing, then bolted the rail to the ledger at given rail anchor locations.

Stripped out even when using the 4mm hex head tool. The hardness of the mounting screw is poor

Head strips out too easily

The metal is cheap. Allen head stripped when i applied the torque necessary to fasten into pressure treated lumber.

too soft the hex stripped out before it was even 1/2 inch in

The socket slot strips at the least bit of resistance. Save yourself all the frustration I went through buying several packs of these to get 3 screws to seat properly. Still have to buy one more pack of these pieces of junk because I still have one leg on my project that isn't connected wish me luck because I wouldn't be overly surprised if every one stripped out on me. Find ANY OTHER WAY to put your project together.
