(Pack of
10)
• Countr-Bor Screws generate higher clamp loads because they are torqued through an external drive (socket); standard hex socket head screws are torqued by an internal drive (hex key)
• Heat-treated alloy steel
• Class 3A UNC threads
• Tensile strength: 180,000 PSI (up to and including 1/2" dia.); 170,000 PSI (over 1/2" dia.)
• ANSI Specification B1.1
• All dimensional properties meet IFI-115 and SAE J58 specifications
• Lawson Countr-Bor Screws can replace any standard hex socket head screw
• 12-point screw fits into same counter-bore hole – use standard 12 point socket
