Ground Anchor for Surface Plate

Ensure absolute stability and repeatable accuracy for your surface plates and machine tools with our heavy-duty Ground Anchor. Designed specifically for precision metrology environments, this anchor (also called an adjusting bolt) provides dependable support, easy height correction and long service life—so your inspection, layout and machine-installation work stays true.

Key benefits

· Robust support for surface plates and machine tools — engineered to withstand substantial loads while minimizing contact damage to expensive precision surfaces.
· Smooth, repeatable adjustment — the threaded screw allows convenient upward and downward adjustment and repeated fine-tuning without compromising accuracy.
· Wide load range and size options — choose the size and load capacity that fits from light-duty fixtures to large heavy plates.
· Durable construction for shop environments — built to resist deformation under pressure so your setup remains stable over long service cycles.
· Simple to install and service — straightforward mounting and adjustment mean faster setup and less downtime.

Typical applications

· Securing and leveling granite and cast-iron surface plates.
· Supporting machine beds, inspection tables and fixture bases during installation and calibration.
· Temporary or permanent anchoring during hand scraping, reconditioning and precision layout work.
· Use with leveling jacks, pads and modular support systems to achieve final flatness and stability.

Features

· High load capacity options (multiple sizes available) to suit light to heavy plates.
· Low surface-impact design to reduce wear on plate faces compared with conventional adjusting bolts.
· Fine screw adjustment for precise vertical control (repeatable travel range suited to metrology needs).
· Multiple length and diameter specifications to match different plate thicknesses and installation depths.
· Hardened/finished components designed for long life and reliable repeatability in industrial settings.

Why choose our Ground Anchor

· Engineered for metrology: manufactured to support precision work where stability and minimal surface impact matter.
· Flexible options: multiple sizes and load ratings let you pick an anchor that matches the exact demands of your surface plate or machine installation.
· Supports long-term accuracy: robust materials and proven thread mechanisms reduce settling and maintain alignment across repeated jobs.
· Expert support & customization: OEM/ODM options available — tell us your special requirements and we’ll configure anchors to fit.
