The unique ”Tight-Squeeze” is a full function hand tool for Hi-Lok® fastener installation. This amazing tool does just what the name implies. It gets into tight places, and allows one-handed Hi-Lok® installation. No more struggling in blind areas, around corners, inside cavities, trying to hold a hex key with one hand and work the Ratchet with the other.The ”Tight-Squeeze” works just like the expensive and bulky pneumatic installation tools, but can go anywhere. Interchangeable hex keys and sockets fit an entire range of pin and collar combinations. Works for aluminum, steel and smaller titanium collars. It saves time and frustration while turning seemingly impossible jobs into routine work.
