The HI-TIGUE™ system has been the first practical interference fit fastening system to be developed. It provides improved fatigue benefits by combining the hole-improvement qualities of the HI-TIGUE™ pin and the consistent preloading qualities of the HI-LOK™ collar.

This fastener has all the features of a Hi-Lok ™ fastener and provides a unique HI-TIGUE ™ fastener bead design. The HI-TIGUE ™ is primarily used wherever structural assembly operations demand controlled preload, automatic torque control and self-locking capabilities.

The Hi-Tigue® fastener offers all of the benefits of the Hi-Lok® fastening system along with a unique bead design that enhances the fatigue performance of the structure making it ideal for situations that require a controlled interference fit.

航空航天或飞机紧固件，一种 CNC加工航空零件 特别适用于航空结构件的生产。 飞机细节部件在许 多生产地点组装，而不是在单一工厂生产。 此外，这些紧固件对于在最终飞机组装中将这些部件连接成完整的飞机是必需的。 航空航天业在安全和重量方面非常严格。 因此，用于制造飞机的紧固件质量上乘且极其耐用。 紧固件还可以组装飞机结构，例如机身、机翼、尾翼、机鼻、吊架、机舱、飞行控制面等。 此外，它们还为商用和军用飞机设计提供了吸引力和耐用性。 此外， …

A bead encircles the bottom of the Hi-Tigue unique fastener’s shank. The bead increases joint strength by preloading the hole it fills. It presses against the hole’s walls during installation, creating radial stress that reinforces the surrounding area.

HSTOOLING Air Driver Assemblies are designed specifically for installing HI-SHEAR CORPORATION HI-LOK™ (*), HI-LITE™, and HI-LOK™/HI-TIGUE™ pin and collar fastener combinations. They come in a variety of sizes and configurations, to drive fasteners in both open and restricted-access areas.

HI-LOKTM HI-TIGUETM Product Specification 342 . First dash number indicates nominal diameter in 1/32nds of the pin which HLT434 oversize pin replaces. Second dash number indicates maximum grip in 1/16ths. See Finish note for explanation of code letters.

The Hi-Tigue fastening system provides improved fatigue benefits by combining the hole-improvement qualities of the Hi-Tigue Pin and the consistent preloading qualities of the Hi-Lok Collar. We stock a wide range of both the pins and collars under the HLT part numbers as well as under OEM drawings like Bombardier and Boeing.
