The Simpson Strong-Tie HL57 is a heavy-duty, L-shaped utility angle engineered to reinforce right-angle connections between structural wood members. Fabricated in the United States from zinc-galvanized steel with a G90 coating, the HL57 delivers reliable corrosion resistance alongside the structural performance demanded in framing and timber applications. Its versatile 90 deg. profile promotes corner stability while helping standardize connections across a wide range of construction scenarios, supporting both construction economy and structural integrity.

Frequently Asked Questions

What are the dimensions of the HL57 angle?

The HL57 has a Width-1 of 5-3/4 in., a Width-2 of 5-3/4 in., and a length of 7-1/2 in., forming a symmetrical L-shaped profile suited for right-angle connections between structural wood members.

What type of corrosion protection does the HL57 have?

The HL57 is coated with a G90 zinc galvanized finish, which provides reliable corrosion resistance and makes it suitable for framing and timber applications where exposure to moisture is a concern.

Can the HL57 resist both uplift and lateral forces?

Yes. The HL57 is engineered to resist both uplift and lateral forces. When installed in pairs, it is capable of achieving lateral load resistance in both directions, making it effective for corner framing reinforcement and beam-to-post connections.

What types of connections is the HL57 approved for?

The HL57 is approved for right-angle connections between structural wood members, corner framing reinforcement in wood construction, beam-to-post and member-to-member connections at 90 deg. angles, and applications requiring resistance to uplift and lateral forces.
