Product Description
10-24 UNC A2 stainless steel round slotted machine screws, manufactured for imperial UNC threaded fastening applications. These round head machine screws are made from A2 stainless steel, giving good corrosion resistance for general indoor, outdoor and damp applications.
The round head gives a traditional raised finish, while the slotted drive is suitable for restoration work, classic applications, panels, brackets, equipment, machinery and general assembly where a plain slot drive is preferred. These screws use a 10-24 UNC Unified National Coarse thread with 24 TPI and are suitable for use with compatible tapped holes or UNC nuts.
For imperial machine screws, the suitable dimensional standard is ASME B18.6.3, with ASME B1.1 covering the UNC thread form. Available in 1/4" length, with pack sizes suitable for single repairs, workshop use and bulk stock.
