Exactly as described

Bought these for a workshop bench. They match the description perfectly. The crescent shape allows for a tight fit in corners where round washers wouldn't work.

Perfect for my standing desk build

These half-moon connectors were exactly what I needed to join the legs of my custom standing desk. The M8 threading is precise, and the zinc finish looks professional. Highly recommend for DIY furniture projects.

Great value for money

You get a lot of pieces for the price. I have plenty left over for future repairs. The half-round design is unique and very effective for edge connections.

Good quality, fast shipping

The washers are sturdy and fit well. I used them to repair an old office chair. One star off only because the packaging was a bit battered, but the parts inside were fine.

Decent but instructions missing

The hardware itself is good quality steel, but I wish there was a small diagram included for the best orientation during installation. Had to figure it out by trial and error.

Strong hold for heavy tables

I was worried these might be too small for my large dining table connector, but they held up perfectly under significant weight. The four-in-one design makes assembly much faster.

5 FAQ

Q: What is the inner diameter of the hole?

A: The inner diameter is designed specifically for M8 bolts, which typically means an 8mm clearance to ensure a snug but manageable fit.

Q: Can I use these with wooden screws instead of machine bolts?

A: These are designed to work with M8 machine bolts or threaded rods. They may not function correctly with standard wood screws that do not have an M8 thread pitch.

Q: Is there a maximum weight limit for these connectors?

A: While we do not specify an exact weight limit as it depends on the entire assembly structure, these are made from high-strength carbon steel and are rated for standard heavy-duty furniture applications like desks and tables.

Q: Does the package include the matching bolts?

A: No, this package contains only the Crescent Half-Round Washers/Connectors. Bolts and nuts must be purchased separately to match the M8 specification.

Q: Are these washers suitable for outdoor furniture?

A: While they are zinc-plated for some corrosion resistance, we recommend using them primarily for indoor furniture. For outdoor use, please consider applying an additional sealant or using stainless steel alternatives.
