Review: As described - Does what it should.. good quality and strong
Review: Perfect. - Perfect for the job: Strong, well-made, simple! Shame the delivery driver didn't knock on my door, but just threw the package over the garden gate. Luckily my neighbour found it later that day!

## Features

- 304 Stainless Steel: The black connection screws are made of 304 stainless steel, anti-rust and anti-corrosion, able to be used in outdoor or wet environment. The surface treatment process of the screws is oxidised black, not electroplated black zinc, which is not easy to fade, scratch-resistant, and more coordinated with some black equipment.
- Unique design: the head of the connecting screws is rounded on the outside and concave hexagonal in the middle, and the edges of the head are chamfered, so that the bolt will not easily scratch or damage the surrounding parts when assembled, and maintains the finish and aesthetics of the parts.
- Stable connection: Belt buckle binding bolts are precision processed, the threaded joints have fine surface treatment, smooth and flat, neat and clear threads, and even force, which ensures a close fit between the two, effectively prevents loosening, and improves the stability and reliability of the connection.
- Easy Installation: Furniture bolts and socket nuts are very easy to install, you just need to drill holes in the board, insert the screws and then tighten them with a spanner. Chamfered screws and socket nuts are usually used to connect furniture parts, furniture connectors can be opened and reinstalled when needed.
- Package includes: 10 x sleeve nuts M4 x 20mm + 10 x furniture bolts M4 x 10mm. Hexagon furniture bolts can be used to mount beds, doors, tables, chairs, worktops, cabinets, wardrobes and other furniture. We offer a wide range of socket nuts and socket screws to meet different fastening needs.
