Simpson Strong-Tie 5/8" x 4-1/4" Hex-Head Sleeve-All Expanding Anchor is a pre-assembled, expanding sleeve anchor engineered for secure fastening into solid base materials such as concrete and brick. Built from zinc-plated carbon steel, this hex-head anchor delivers reliable holding strength in demanding structural and general construction applications - from infrastructure projects to DIY installations. The 5/8" diameter with a 1/2" bolt size and hex-head configuration makes it straightforward to drive and tighten with standard tools, giving contractors and builders a dependable fastening solution across a wide range of project types.

Key Features

• Pre-assembled expanding sleeve design - arrives ready to install with no separate components to lose or align, saving time on the job site and reducing installation errors in solid base materials.
• Hex head configuration with 3/4" wrench size - compatible with standard wrenches and sockets for fast, controlled installation without specialty tooling.
• 5/8" diameter with matching 5/8" drill bit requirement - the hole and anchor diameter are identical, ensuring a snug, well-seated fit that maximizes holding performance in the base material.
• 1/2" bolt diameter with 13 TPI threading - coarse thread pitch resists loosening under vibration and load, supporting secure connections in structural applications.
• Zinc-plated carbon steel construction - the zinc coating provides corrosion resistance for general indoor and protected outdoor environments, extending the service life of the anchor in typical construction conditions.
• Maximum fixture thickness of 1-1/2" - accommodates a range of mounting plates and structural members, giving installers flexibility when securing hardware, equipment, or framing components to concrete or masonry.

Why This Product

• The pre-assembled sleeve design eliminates the need to handle loose parts during installation, making it a practical choice for overhead, one-handed, or high-volume fastening work in solid concrete or brick.
• The hex-head style with a defined 3/4" wrench size means no guesswork on tooling - installers can prepare ahead and complete fastening quickly and consistently across multiple anchor points.
• With a 5/8" anchor diameter and corresponding drill bit size, the fit between the bored hole and the expanding sleeve is optimized for maximum engagement and pull-out resistance in solid base materials.
• Simpson Strong-Tie's engineering focus on mechanical anchors means this sleeve anchor is designed to perform reliably in demanding structural applications where consistent clamping force and vibration resistance matter.

Frequently Asked Questions

What drill bit size is required to install this sleeve anchor?

A 5/8" drill bit is required. The drill bit diameter matches the anchor diameter exactly, ensuring the expanding sleeve seats properly within the drilled hole for a secure, snug fit in solid base materials like concrete and brick.

What wrench size is needed to tighten this hex-head anchor?

A 3/4" wrench is the correct size for this anchor's hex head. Using the correct wrench size ensures proper torque application without damaging the head or under-tightening the expanding sleeve.

What types of base materials is this sleeve anchor designed for?

This Sleeve-All expanding anchor is designed for use in all types of solid base materials, including concrete and brick. It is not intended for hollow or non-solid substrates - always confirm the base material is solid before installation.

What is the maximum fixture thickness this anchor can accommodate?

This anchor supports a maximum fixture thickness of 1-1/2". When installing mounting plates, structural members, or equipment bases, ensure the material being fastened does not exceed this thickness to maintain proper thread engagement and clamping performance.
