Tension control bolts, also called TC Bolts, are an assembled unit including a bolt, washer, and nut. The bolt has a rounded head and specialized tip at the end of the threaded shaft. During installation, the specialized tip will shear off after the appropriate tension has been applied. This key feature safeguards the consistency and integrity for each bolt installed. All three components are structural grade; the bolts are offered in A325 and A490 grade. The hex nuts are A563 grade and washers are F436 grade.
