Materials
The made-in-the-USA GRIP-TIGHT™ Nut is produced from through-hardened carbon steel and each free spinning washer is made from through-hardened and tempered chrome-moly steel. The GRIP-TIGHT™ Nut geometry and coatings combine to create a consistent and efficient translation from torque to clamping force.
Design
GRIP-TIGHT™ Nuts have M22X1.5 threads, 33mm hex, 27mm height and a 46mm washer diameter. The two-piece GRIP-TIGHT™ Nuts comply with technical requirements of SAE J1965. Cross Reference PN’s: 39773, 39874, 39702, M3979, 39691, 39949, 201.3013, 13-3057, E-9020, W-525, R009020, 511034, KB9020,WA075037, 20857204, 1649492C1, E6HZ-1120-A, MF110343, and MF111026.
Loading Surface
GRIP-TIGHT™ Nuts can be torqued and loosened with common impact guns and wrenches. The patent pending washer profile includes a special geometry for rotationally coupling to the HYTORC reaction socket. This washer acts as a coaxial reaction point, thereby eliminating pinch points and removing undesirable side loads. These benefits make it feasible to upgrade to cordless digital tooling systems while increasing the efficiency, quality and safety of wheel nut installations.
