The square steel threaded spring inserts are manufactured using a high-quality spring steel for heavy duty applications. The 307 spring series inserts are unique in the sense that they allow for the spring portion of the insert to expand once inside a tube or pipe, providing for a tight fit. We have a range of thread diameters including 7.9 mm (5/16"), and 9.5 mm (3/8"). The outer square diameter measurements are 19.5 mm (3/4?), 22.3 mm (7/8"), 25.4 mm (1"), 31.8 mm (1-1/4"), 38.1 mm (1-1/2") and 50.8 mm (2").
