Flat countersunk nib bolts

The flat head of Flat countersunk nib bolts can be completely embedded in the material surface. Using it will not cause surface protrusion. There is a small tenon under the head and the screw has threads.

Product details

The bolt can fix anti-slip composite plates to steel frames. Even in the case of slippery rain, the bolt heads can firmly grasp the frame holes to prevent rotation during tightening. To prevent tripping over protruding parts, it will not loosen like standard bolts due to continuous vibration by children.

Flat countersunk nib bolts can be used to fix thin control cabinet panels. They can be used in places where standard bolts cannot be used. After insertion, the bolt head will immediately snap into the sheet metal hole to lock the bolt head. They can prevent wire entanglement during maintenance and keep the surface of the casing clean, tidy and professional.

The bolt can be used to install plastic debris protection devices on tractors. They can withstand vibrations. The bolt head passes through the mud accumulation and is locked in the stamped steel hole. They do not accumulate crop residues like protruding fasteners. Farmers can quickly disassemble/replace cracked protective devices during seasonal maintenance without having to painstakingly rotate the bolts.

Product selling point

The tenons of Flat countersunk nib bolts are very practical. The tenon precisely matches the groove or hole drilled in the material. During installation, insert the bolt, and the tenon will hold the groove wall. When tightening the nut, the bolt will not rotate. When installing ironwork fences, workers can operate the nuts with one hand.
