The Simpson PAB7-30 Pre-Assembled Anchor Bolt from Simpson is a cast-in-place anchor bolt engineered for high-tension-load applications, including rod systems and shearwall anchor bolt connections. At its embedded end, a plate washer is sandwiched between two fixed hex nuts, creating a robust mechanical interlock within the concrete. Each bolt ships fully pre-assembled - including one anchor bolt, one plate washer, and two hex nuts - so it arrives jobsite-ready with no additional hardware to source or assemble.

Key Features

• 7/8 in. rod diameter, 30 in. rod length - sized for demanding structural connections where a larger-diameter anchor bolt is required to handle elevated tension loads.
• Plate washer sandwiched between two fixed hex nuts at the embedded end - forms a secure mechanical interlock in the concrete, directly supporting high-tension-load performance in rod systems and shearwalls.
• Head stamp with the Simpson Strong-Tie No Equal sign and diameter designation - allows fast, accurate identification of the bolt after the concrete pour is complete, reducing the risk of installation errors on busy job sites.
• Available in diameters from 1/2 in. to 1 1/4 in. and lengths from 12 in. to 36 in. in 6 in. increments - gives engineers and contractors the flexibility to specify the right anchor bolt size for each unique structural application.
• Manufactured from steel meeting ASTM F1554 Grade 36, A36 or A307 standards - meets widely recognized structural steel specifications, supporting confidence in load-rated design and code compliance.

Why This Product

• Purpose-built for high-tension-load structural connections - the pre-assembled plate washer and dual hex-nut configuration at the embedded end is specifically designed for demanding applications like cast-in-place rod systems and shearwall connections, where anchor bolt pull-out resistance is critical.
• Arrives ready to set in the form - the bolt, plate washer, and both hex nuts come pre-assembled as a single unit, eliminating on-site assembly steps and reducing the chance of a component being omitted before the pour.
• Straightforward post-pour verification - the stamped head marking lets inspectors and installers quickly confirm anchor bolt identity and diameter without referencing separate paperwork, saving time during inspection and follow-up work.
• Broad size range supports consistent sourcing across projects - with multiple diameter and length combinations available within the same PAB product family, contractors can standardize on one trusted cast-in-place anchor bolt line across a variety of structural layouts.

Frequently Asked Questions

What makes the PAB7-30 suitable for high-tension-load applications?

The PAB7-30 features a plate washer at the embedded end sandwiched between two fixed hex nuts. This assembly creates a strong mechanical interlock within the concrete, making it ideal for demanding high-tension-load applications such as rod systems and shearwalls.

What material and steel grade is the PAB7-30 made from?

The PAB7-30 is manufactured from uncoated steel meeting ASTM F1554 Grade 36, A36 or A307 standards, with a minimum tensile strength (Fu) of 58 ksi.

How can the PAB7-30 be identified after the concrete has been poured?

The anchor bolt includes a head stamp that displays the Simpson Strong-Tie No Equal sign along with the diameter designation, allowing for easy identification even after the concrete pour is complete.

What are the rod dimensions of the PAB7-30, and are other sizes available?

The PAB7-30 has a rod diameter of 7/8 in. and a rod length of 30 in. The PAB series is available in diameters from 1/2 in. to 1-1/4 in. and lengths from 12 in. to 36 in. in 6-in. increments.
