Key Features

• Expansion anchor for solid base materials - works in concrete, brick, and other solid substrates, giving you dependable holding power across a wide range of construction and fastening applications.
• FM and UL approved with multiple DOT listings - independently verified for safety and performance, so you can use this anchor with confidence on regulated infrastructure and structural projects.
• Phillips flat head design - sits flush against the fixture surface for a clean, low-profile finish that is compatible with standard Phillips-drive tools you likely already own.
• 3/8 in. drill bit size required - matched hole sizing promotes a secure, tight fit; avoiding oversized holes is critical to maintaining the anchor's full load capacity.
