CSK Socket UNF Screws
Countersunk (CSK) Socket Screws – UNF Thread
Our Countersunk (CSK) Socket Screws with UNF (Unified Fine) threads are precision-engineered fasteners designed to provide a secure, flush finish for a variety of applications. The countersunk head allows the screw to sit flush or below the surface of the material, delivering a smooth, professional appearance without protrusions.
Featuring a hex socket drive, these screws offer reliable torque transmission and easy installation using an Allen key or hex wrench, minimizing the risk of stripping. The fine thread profile of UNF screws provides greater tensile strength and better resistance to loosening, making them ideal for high-stress or vibration-prone environments.
Available in multiple sizes, CSK Socket Screws with UNF threads are commonly used in automotive, aerospace, machinery, electronics, and precision engineering applications where strong, durable fastening with a neat finish is essential.
