Perfect for cross-bracing

We ordered fifty of these for a large commercial site. They align perfectly at 90 degrees and hold the structure rigid. Delivery was fast and packaging prevented any damage.

Great for home projects

Bought these to build a sturdy storage rack in my garage using scaffolding poles. They are over-engineered for home use which is a good thing. Very secure.

Reliable fastener

No complaints here. The bolt heads are hexagonal and easy to grip with a wrench even when wearing gloves. Will definitely order more when we expand the site.

Solid build quality for heavy duty work

These couplers are exactly what we needed for our scaffolding project. The galvanization is thick and the fit on standard pipes is snug without being too tight. Highly recommend for professional use.

Good value, minor threading issue

Overall a great product for the price. One out of ten units had slightly rough threads on the nut, but it still tightened down securely. The steel feels very robust.

Exceeds expectations

I was worried about rust since we are working near the coast, but the hot-dip galvanizing looks excellent. These clamps inspire confidence in the safety of the scaffold.

5 FAQ

Q: Does this come with the bolt and nut included?

A: Yes, each unit comes complete with one M12 bolt, one nut, and one washer ready for immediate installation.

Q: What is the torque specification for the bolts?

A: For optimal safety and performance, we recommend tightening the M12 bolts to a torque of 50 Nm using a calibrated torque wrench.

Q: Can these be used outdoors in rainy conditions?

A: Absolutely. The hot-dip galvanized finish provides excellent corrosion resistance, making them suitable for prolonged outdoor exposure.

Q: Are these compatible with 42mm pipes?

A: These couplers are specifically designed for standard 48.3mm scaffolding pipes. Using them with 42mm pipes may result in a loose fit and compromised safety.

Q: Is there a bulk discount for orders over 100 units?

A: Yes, we offer tiered pricing for bulk orders. Please contact our sales team directly or add 100+ units to your cart to see the automated discount applied.
