self countersunk screws

One of the primary benefits of butterfly screws is their efficiency. Their ergonomic shape enables users to apply torque with ease, making them ideal for applications where frequent assembly and disassembly are necessary. This is particularly useful in industries such as automotive, furniture manufacturing, and even in home DIY projects. The ability to quickly tighten or loosen without tools saves time, effort, and reduces the risk of damage that can occur with the use of incorrect or over-tightened tools.

This expansion generates a powerful frictional force that locks the anchor in place, providing exceptional holding power.
