Hole size: 5mm
External Diameter: 16mm

Material: Stainless Steel
Commonly used in routesetting, especially for low profile handholds / footholds.
It is also used to screw on light duty equipment like jump rope hangers onto wood surfaces, or false walls with the right false wall anchor.
Never use one screw on its own. A typical 4mm screw has a pull out weight of about 60-80kg, depending on the thickness and quality of the plywood or lumber it is attached to.
We recommend to use at least 3 screws per handhold or equipment you are mounting to plywood.
