Core Specification Parameters Common models include C17, C20, C24, C45, etc., and also include internationally universal specifications such as SR8. Different models correspond to different opening sizes and closing diameters: The wire gauge is mostly 15-16GA (wire diameter is approximately 1.6-1.8mm), featuring high strength and being not easy to loosen after crimping. Common opening widths are 17mm, 20mm, 24mm, etc. After closing, multiple strands of steel wire can be firmly locked. Arranged in a single row and in strips, it is compatible with corresponding C-type nail guns (such as SC760, SR8 series), with stable feeding and one-time crimping forming. Performance Characteristics Locking-type fastening: It will close to form a closed loop after crimping, with a gripping force several times stronger than ordinary nails, which can prevent wire meshes and cages from loosening due to pulling. Strong adaptability: It can penetrate multiple strands of steel wire and mesh, and does not rebound or fall off after crimping, making it a special fastener for cage assembly. Rust-resistant and durable: Galvanized/stainless steel materials can resist corrosion in humid and breeding environments, ensuring a long service life.
