Frequently Asked Questions

What type of connection is the HIT318 designed for?

The HIT318 is designed for standard 90-degree connections of I-joists to headers, making it a reliable choice for typical framing applications where a perpendicular joist-to-header connection is required.

What is positive-angle nailing (PAN) and why does it matter for I-joists?

Positive-angle nailing (PAN) is a feature specifically engineered for use with I-joists. It directs nails at an angle that minimizes the risk of splitting the I-joist web or flange during installation, helping to preserve the structural integrity of the joist.

What do the extra triangle holes on the HIT318 do?

The extra triangle holes on the HIT318 allow for higher uplift loads to be achieved. This gives the hanger greater capacity to resist upward forces, which is particularly beneficial in applications subject to wind uplift or other uplift-generating loads.

What finish does the HIT318 have, and what gauge steel is it made from?

The HIT318 features a Zinc Galvanized, G90 finish for corrosion resistance and is constructed from 16-gauge steel, providing the heavy-duty strength required for demanding structural connections.
