Product Description
Stainless Steel Spring Bolt 165mm × 12mm with Countersunk Holes
The Factory Yard Stainless Steel Spring Bolt with Countersunk Holes is designed for applications requiring a secure, reliable and flush-mounted locking solution. Manufactured from corrosion-resistant AISI 304 stainless steel, this heavy-duty spring-loaded bolt provides smooth operation and dependable performance in demanding indoor and outdoor environments.
Unlike standard fixing plates, the countersunk mounting holes allow screw heads to sit flush with the bolt body, creating a cleaner appearance while reducing the risk of snagging, accidental impact or tampering.

Ideal for OEM manufacturers, installers and maintenance professionals, this spring bolt offers long service life with minimal maintenance.
