Simpson Strong-Tie 1/2" x 4" Hex-Head Sleeve-All Anchor is a pre-assembled, expanding sleeve anchor engineered for secure, reliable fastening in solid base materials such as concrete and brick. Designed by Simpson Strong-Tie for both demanding structural applications and everyday installation tasks, this carbon steel anchor with a zinc plated finish delivers consistent holding performance wherever a strong mechanical connection is required. The hex head style allows straightforward tightening with a standard wrench, making it a practical choice for professionals and do-it-yourself builders alike.

Key Features

• Pre-assembled expanding sleeve design - arrives ready to install with no separate components to manage, saving time and reducing setup errors on the job site.
• Hex head style with 9/16" wrench size - compatible with standard wrenches for fast, controlled tightening and secure seating in the base material.
• 1/2" anchor diameter with 1/2" drill bit requirement - the anchor diameter matches the required drill bit size exactly, simplifying hole preparation and ensuring a snug, expansion-ready fit.
• 3/8" bolt/rod diameter at 16 TPI - provides a standardized thread pitch that is compatible with common threaded rod and bolt hardware, broadening its range of attachment options.
• Carbon steel construction with zinc plated finish - delivers structural strength while the zinc plating provides a layer of corrosion resistance for extended service life in typical interior and protected applications.
• Maximum fixture thickness of 1-3/4" - accommodates a meaningful range of material thicknesses, allowing secure attachment of brackets, plates, channels, and similar hardware without needing to size up.
• Engineered for solid base materials - performs optimally in concrete and brick, base materials common to infrastructure, commercial, and residential construction projects.

Why This Product

• The pre-assembled, one-piece sleeve construction eliminates loose parts and streamlines installation in high-volume anchoring tasks - fewer steps mean faster, more consistent results across a full project.
• With a 1/2" anchor diameter and matching 1/2" drill bit requirement, there is no guesswork in hole sizing - the anchor installs flush and expands reliably in the prepared opening.
• The zinc plated carbon steel build balances structural load capacity with corrosion resistance, making this anchor appropriate for a broad range of indoor and protected structural applications without the cost of stainless or hot-dip galvanized alternatives.
• Simpson Strong-Tie's mechanical anchor line is designed to perform across complex infrastructure projects and lighter-duty installations alike, giving buyers a trusted, versatile anchoring solution from a recognized brand in structural connectors and fasteners.

Frequently Asked Questions

What base materials is the Simpson Sleeve-All anchor designed for?

This anchor is designed for use in solid base materials, including concrete and brick. It is a mechanical expanding sleeve anchor and is not intended for use in hollow or unsupported substrates.

What drill bit size should I use to install this anchor?

The required drill bit diameter for this anchor is 1/2". Using the correct bit size ensures the sleeve fits snugly in the hole and expands properly upon tightening for a secure hold.

What wrench size is needed to tighten the hex head?

A 9/16" wrench is required to drive and tighten the hex head on this anchor. Standard open-end, box, or socket wrenches in that size will work with this fastener.

What is the maximum fixture thickness this anchor can accommodate?

This anchor supports a maximum fixture thickness of 1-3/4". This refers to the thickness of the material - such as a bracket, plate, or channel - being fastened to the base material. Fixtures thicker than 1-3/4" would require a different anchor length or size.
