Unisorb Heavy Duty Jakebolts
Unisorb Heavy Duty Jakebolts are cast-in-place anchor bolts designed for concrete foundations and machinery installations where adjustability and long-term reliability matter. They are hung from a template or welded to reinforcing steel before the foundation pour. The all-steel, watertight housing helps protect internal components during installation and grouting, and the retractable stud design supports a clear floor condition when needed.
Key Features
- All-steel construction with MIG welded, watertight housing to help prevent contamination during installation.
- Retractable studs support a clear floor condition when required.
- Centralizing bushing doubles as a seal and helps protect against contamination during grouting.
- Adjustable stud projection from 0 to 6 inches or 0 to 12 inches, depending on the model.
- Internal anchor assembly adjusts laterally and vertically to compensate for normal construction variances.
- Bolt material uses 90,000 psi tensile strength steel.
Applications
- New machine foundation construction where anchors are cast in place.
- Machinery base anchoring where vertical and lateral adjustment helps accommodate hole location variation.
- Installations where stud retraction is needed for maintenance, changeovers, or floor clearance.
- Concrete foundation and equipment anchoring in severe service conditions.

Frequently Asked Questions
How are Heavy Duty Jakebolts installed?
They are designed to be hung from a template or welded directly to reinforcing steel, then cast in place during new foundation construction.
Can I retract the studs after installation?
Yes. The retractable stud design allows a clear floor condition when needed.
What projection ranges are available?
Anchor studs can be adjusted to project above the floor from 0 to 6 inches or from 0 to 12 inches, depending on the model specified.
Do the anchors allow for alignment adjustment?
Yes. The internal anchor assembly can be adjusted laterally and vertically to compensate for normal construction variances in hole location and machine foot thickness.
What bolt sizes are available?
Standard bolt diameters range from 1/2 inch (12.5 mm) to 2 inch (50.8 mm).
