The Simpson AnchorMate 1/2 in. Anchor Bolt Holder is a reusable composite polymer holder engineered to keep 1/2-in. diameter anchor bolts precisely positioned in concrete formwork before and during a pour - a requirement in some jurisdictions. The threaded gripping section locks each bolt firmly at a consistent location and height without requiring a nut, speeding up both setup and teardown while protecting threads from splashing wet concrete. Built-in stops for 2x4 and 2x6 form members and elevated bolt grippers make this holder a practical, time-saving solution for foundation, slab, and mudsill anchor bolt placement on residential and light commercial projects.

Key Features

• Built-in 2x4 and 2x6 stops - automatically position the holder on the form board, eliminating manual measuring and reducing layout errors during installation.
• Threaded grippers secure the bolt without a nut - holds each anchor bolt at a consistent location and height for faster setup and teardown compared to nut-dependent methods.
• Elevated bolt grippers - keep threads clear of splashing concrete and give finishers unobstructed trowel access to the slab surface for cleaner finishing work.
• Thread protection during the pour - shields anchor bolt threads from wet concrete, helping to ensure bolts remain clean and ready for mudsill or sill plate installation.
• Color-coded yellow - provides instant on-site identification for 1/2-in. diameter bolts, reducing mix-ups when multiple anchor bolt sizes are in use.
• Reusable composite polymer construction - lightweight and durable enough for repeated use across multiple pours, yet cost-efficient for single-application jobsites as well.

Why This Product

• Faster concrete formwork setup - the nut-free threaded gripper design and built-in form board stops work together to cut layout and installation time, letting crews move efficiently from forming to pouring.
• Consistent, accurate bolt placement every time - grippers hold each anchor bolt at the same location and height across the entire pour, reducing the risk of misaligned bolts that slow down framing and mudsill installation.
• Protects your investment in hardware - by shielding threads from wet concrete during the pour, the holder helps ensure anchor bolts arrive at the framing stage clean and undamaged, avoiding costly rework or replacement.
• Reusable design lowers per-project cost - made from durable composite polymer and designed to be reused, this holder delivers value on multi-pour projects while remaining practical for one-time use when needed.

Frequently Asked Questions

What anchor bolt diameter is the AM 1/2 designed to hold?

The AM 1/2 AnchorMate is designed specifically for 1/2-in. diameter anchor bolts. It is color-coded yellow for instant on-site size identification, helping to prevent mix-ups when multiple bolt sizes are in use.

Does the AnchorMate require a nut to secure the anchor bolt in place?

No. The threaded grippers hold each bolt firmly at a consistent location and height without requiring a nut. This nut-free design speeds up both setup and teardown compared to traditional positioning methods.

Which form board sizes are compatible with the AM 1/2?

The AM 1/2 includes built-in stops sized for both 2x4 and 2x6 form members. These stops automatically position the holder on the form board, eliminating the need for manual measuring during installation.

Can the AM 1/2 be reused across multiple pours?

Yes. The AM 1/2 is designed to be reusable, making it cost-efficient for both single-application and multi-pour projects. It is made from a lightweight, durable composite polymer material that withstands repeated use.
