The Simpson 8x3/4 Carbon Steel Screen Tube for Epoxy is a 60 mesh carbon steel screen tube engineered by Simpson for post-installed anchor rod installations in hollow base material applications. When epoxy adhesive is dispensed into a hollow substrate, voids in the material can cause adhesive to migrate away from the anchor, compromising bond strength - this screen tube solves that problem by containing the adhesive directly around the rod and precisely controlling how much passes through the mesh. Compatible exclusively with Simpson ET-3G epoxy adhesive formulations, it delivers thorough, consistent coating and bonding of the rod to the screen tube and surrounding base material.

Key Features

• Designed for hollow base material anchoring - contains adhesive around the anchor and prevents it from running into voids, ensuring a reliable bond in substrates where adhesive loss is a real concern
• 60 mesh carbon steel construction - precisely controls the volume of adhesive passing through the mesh, resulting in thorough, even coating and bonding of the rod to the screen tube and base material
• Sized for 3/4-in. rod diameter - matches common anchor rod sizing for a properly fitted installation with no guesswork
• Must be paired with ET-3G epoxy adhesive formulations - the mesh is specifically calibrated for ET-3G flow characteristics, so using the correct adhesive is critical to achieving proper adhesive distribution and bond performance
• Carbon steel material - provides the structural integrity needed to hold its cylindrical form during adhesive dispensing and anchor setting

Why This Product

• Purpose-built for hollow substrate anchoring - unlike general-purpose fastening accessories, this screen tube is engineered specifically to address the challenge of adhesive containment in hollow base materials, where voids would otherwise allow adhesive to escape and weaken the anchor installation
• Adhesive-type matched for consistent performance - the 60 mesh is calibrated to work with ET-3G epoxy adhesive, meaning the adhesive flow rate and coverage are optimized by design rather than left to chance, giving installers confidence in every pour
• Backed by Simpson Strong-Tie engineering - part of a coordinated system of dispensing tools and accessories developed by Simpson to make adhesive anchoring as efficient and repeatable as possible on the job site
• Simple, single-use format - each screen tube is packaged individually, making it straightforward to match quantity to the number of anchor installations needed without waste

Frequently Asked Questions

Which adhesive must be used with the ETS758 screen tube?

The ETS758 epoxy screen tube is specifically designed to work with Simpson Strong-Tie ET-3G epoxy adhesive formulations. Using a different adhesive type with this screen tube is not recommended, as screen tubes are designed for a specific adhesive type to ensure proper adhesive flow through the mesh.

What rod diameter is the ETS758 screen tube designed to accept?

The ETS758 screen tube is sized for a 3/4-in. rod diameter. It has an outside diameter of 31/32 in. and requires a 1-in. drilled hole in the base material.

Why are screen tubes used in hollow base material applications?

Screen tubes are used in hollow base material applications to contain the adhesive around the anchor and prevent it from running into voids within the material. The 60 mesh carbon steel construction of the ETS758 precisely controls the amount of adhesive that passes through, resulting in thorough coating and bonding of the rod to the screen tube and base material.

What is the length of the ETS758 screen tube?

The Simpson Strong-Tie ETS758 screen tube has a length of 8 in., making it suitable for applications that require deeper embedment of the anchor rod in hollow base materials.
