B7 All Thread Rod, Teflon

ASTM A193 Grade B7 all thread rod is manufactured from an alloy which includes chromium-molybdenum steel, quenched and tempered, for added strength and corrosion resistance. Dimensional specifications are governed by ASME B18.31.3. Inch series fasteners meeting ASTM A193 Grade B7 specifications are typically used in flange bolting applications. ASTM A193 covers the requirements for high temperature and high pressure bolting. A193 B7 all thread rod having diameters above 1" are most common in 8UN (8 threads per inch). PTFE coating (commonly referred to as the Dupont trade name Teflon) is formulated with superior characteristics for maximum fastener life. Technical components include a tensile strength of up to 4,000 psi and an operating pressure up to 100,000 psi. The absence of nut locking oxides enable easy and safe removal. PTFE coatings have extreme chemical resistance and are ideal for applications including insulating piping, boiler rooms, water filled piping, water lines and more.
