CSK Socket UNC Screws
Countersunk (CSK) Socket Screws – UNC Thread
Our Countersunk (CSK) Socket Screws with UNC (Unified Coarse) threads are precision-engineered fasteners designed to provide a secure, flush finish for a wide variety of applications. The countersunk head allows the screw to sit flush or below the material surface, offering a smooth, professional appearance without protrusions.
Featuring a hex socket drive, these screws provide reliable torque transfer and easy installation using an Allen key or hex wrench, minimizing the risk of stripping. The coarse thread profile of UNC screws enables faster assembly and excellent resistance to stripping, making them suitable for heavy-duty applications in construction, automotive, machinery, and general engineering.
Available in multiple sizes, CSK Socket Screws with UNC threads are ideal for fastening metal, wood, and composite materials where strength, durability, and a clean finish are required.
