The Simpson 3/8 in. x 2-3/4 in. Phillips Flat-Head Sleeve-All Anchor is a pre-assembled, expanding sleeve anchor from Simpson engineered for secure, reliable fastening in solid base materials such as concrete and brick. Built from zinc-plated carbon steel and featuring a Phillips flat head profile, this anchor is designed to install easily while delivering optimal performance in demanding structural applications - from complex infrastructure projects to everyday construction and renovation work.

Key Features

• Expansion anchor for solid base materials - the sleeve-expansion mechanism locks the anchor firmly in concrete, brick, and other solid substrates, providing a secure hold you can depend on in structural applications
• FM and UL approved with multiple DOT listings - third-party certifications mean this anchor meets strict compliance requirements, making it suitable for regulated infrastructure, commercial, and government projects without additional vetting
• Phillips flat head profile - the low-profile flat head sits flush with the fixture surface, giving a clean, finished appearance while accommodating standard Phillips drive tools already in most toolkits
• Pre-assembled design - the anchor arrives ready to install with no separate components to manage on the job site, reducing setup time and the chance of installation errors
• Zinc-plated carbon steel construction - the zinc plating provides a corrosion-resistant barrier over a strong carbon steel core, helping the anchor maintain integrity in typical interior and sheltered exterior environments
• Requires a 3/8 in. drill bit - a precise hole-to-anchor match is critical; using the correctly sized bit ensures the sleeve sets properly and the anchor achieves its rated load capacity

Why This Product

• Compliance-ready for demanding projects - FM and UL approvals combined with multiple DOT listings mean this anchor can be specified on regulated commercial, infrastructure, and government work without sourcing a separate certified fastener
• Versatile across a wide range of solid-material applications - whether anchoring into poured concrete on a structural job or securing fixtures to brick during a renovation, this expanding sleeve anchor is engineered to perform across the solid base materials most commonly encountered in both professional and DIY settings
• Simplified installation with pre-assembled components - because the anchor ships fully assembled and requires only a standard Phillips driver and a 3/8 in. drill bit, installers can work efficiently without sourcing additional hardware or specialized tools
• Trusted Simpson engineering behind every anchor - Simpson offers a wide variety of mechanical anchoring products designed to meet virtually any need, and the Sleeve-All line reflects that same commitment to easy installation and optimal performance even in the most demanding structural applications
