Simpson Strong-Tie Sleeve-All 1/2" x 2-1/4" Hex-Head Expanding Sleeve Anchor is a pre-assembled mechanical anchor engineered for reliable fastening into solid base materials including concrete, brick, and other masonry substrates. Built from carbon steel with a zinc plated finish, this hex-head sleeve anchor delivers consistent holding performance in demanding structural and general construction applications - from large-scale infrastructure projects to everyday renovation and DIY work. The expanding sleeve design locks firmly in place as the bolt is tightened, creating a secure mechanical connection that installers can count on in solid base material conditions.

Key Features

• 1/2" anchor diameter with a 1/2" drill bit requirement - allows a straightforward, one-to-one hole preparation process so the anchor fits precisely without guesswork or oversized holes that reduce holding strength.
• 3/8" bolt/rod diameter with 16 TPI threading - the coarse 16 threads-per-inch pattern provides strong engagement and resistance to loosening under vibration or load cycling in structural applications.
• Hex head configuration requiring a 9/16" wrench - the hex head allows standard wrench or socket installation for controlled, consistent torquing without specialized tooling.
• Zinc plated carbon steel construction - the zinc plating provides a corrosion-resistant barrier over the carbon steel body, extending service life in typical indoor and sheltered construction environments.
• Maximum fixture thickness of 1/2" - clearly defined clamping range so you can match the anchor to your exact fixture and base material combination with confidence.
• Pre-assembled expanding sleeve design - the anchor arrives ready to install with no separate components to assemble on-site, reducing installation time and the chance of assembly errors.
• Compatible with all types of solid base materials - concrete, brick, and other solid masonry substrates are all valid installation environments, giving this anchor broad applicability across project types.

Why This Product

• The pre-assembled expanding sleeve eliminates on-site component assembly, making it a practical choice for contractors and builders who need efficient anchor installation without sacrificing holding integrity in solid masonry.
• The hex head style with a defined 9/16" wrench size means installers can use standard hand tools or power tools fitted with a socket - no proprietary driver bits or special equipment needed to complete the installation.
• Carbon steel with zinc plating offers a durable combination for typical construction environments, providing a corrosion-resistant surface that holds up in sheltered or semi-exposed conditions where bare steel would degrade.
• With a 1/2" anchor diameter directly matching the required drill bit size, hole preparation is exact and straightforward - reducing the risk of loose fits, misaligned holes, or reduced pullout resistance caused by oversized bores.

Frequently Asked Questions

What base materials is this expanding sleeve anchor designed for?

These Sleeve-All anchors are designed for use in all types of solid base materials, including concrete and brick. They are not intended for hollow or unsupported voids - a solid substrate is required for the expanding sleeve to grip properly and develop full holding strength.

What drill bit size do I need to install this anchor?

A 1/2" diameter drill bit is required to prepare the hole for this anchor. The drill bit diameter matches the anchor diameter exactly, ensuring a precise fit that allows the expanding sleeve to engage the base material correctly when tightened.

What wrench size is needed to install the hex-head anchor?

A 9/16" wrench or socket is required to drive and tighten this hex-head sleeve anchor. This standard size is compatible with common hand tools and power tool socket sets, so no specialized equipment is needed for installation.

What is the maximum fixture thickness this anchor can accommodate?

The maximum fixture thickness for this anchor is 1/2". When selecting this anchor for your application, confirm that the material being fastened does not exceed this thickness to ensure proper seating of the anchor head against the fixture surface and full engagement of the sleeve within the base material.
