The Simpson Strong-Tie HL55HDG-5/8 is a heavy-duty, hot-dip galvanized L-shaped angle engineered to reinforce right-angle connections between structural wood members. Built to a robust 7-gauge steel construction and finished with a hot-dip galvanized coating for superior corrosion resistance, this versatile connector improves corner stability while promoting standardization and construction economy. Its symmetrical 5-3/4" x 5-3/4" leg widths and 5/8" bolt holes make it a dependable solution wherever two members meet at a 90 deg. angle and structural integrity is non-negotiable.

Frequently Asked Questions

What size bolt holes does the HL55HDG-5/8 have, and what fasteners are compatible?

The HL55HDG-5/8 features 5/8" diameter bolt holes, which are sized to accommodate standard 5/8" structural bolts or equivalent lag screws.

What are the leg dimensions of this angle connector?

Both legs of the HL55HDG-5/8 measure 5-3/4" wide, and the connector has an overall length of 5". The symmetrical design makes it equally suited for both sides of a right-angle connection.

What type of corrosion protection does this connector have, and where is it best used?

The HL55HDG-5/8 is finished with a hot-dip galvanized (HDG) coating, which provides long-lasting corrosion resistance. This makes it well suited for exterior, exposed, or moisture-prone structural applications where standard zinc-plated connectors may not offer sufficient protection.

Can this angle connector resist forces in multiple directions?

Yes. The HL55HDG-5/8 is designed to resist both uplift and lateral forces. When installed in pairs, it can achieve lateral load resistance in both directions, making it a reliable choice for reinforcing right-angle connections between structural wood members where multi-directional strength is required.
