Precast Concrete Coil Inserts

CN1 Standard and CN2 Heavy Duty Coil Nuts are designed for use with Coil Bolts and Coil Rods in concrete formwork, precast anchoring and bridge formwork applications. Their self-cleaning coarse threads enable fast installation, easy removal and repeated reuse.

HULK Metal CB1, CB2 and CB3 coil bolts thread into embedded coil inserts to create secure lifting, bracing, tie-down and fixing points in precast concrete. Self-cleaning coil threads, forged hex heads and high-quality steel deliver dependable performance in 3/4", 1" and 1-1/4" sizes.

Magnetic coil thread protectors lock instantly onto exposed threadbar and coupler threads before casting, keeping concrete slurry and debris out of the thread profile. Magnetic self-retention speeds installation and removal, and full reusability cuts daily consumable cost in precast production.

Forged steel swivel lift plates connect embedded lifting inserts to crane hooks for precast concrete face and edge lifting. Single plates suit 3/4" and 1" bolts. Double plates rotate 360° horizontally and 180° vertically for 1" to 1-1/2" bolts. All rated at 5:1 SWL.

The HULK Coil Disk Anchor is a low-profile, coil-threaded anchorage insert embedded in precast concrete. Its disk base spreads load over a wide area, providing reliable pull-out resistance for lifting, bracing, and tie-down applications in slabs, panels, and thin elements.

​The HULK Standard Slab Coil Insert is a general-purpose lifting and anchoring component engineered for medium-thickness precast concrete slabs. It provides dependable working loads, quick installation, and secure attachment points for handling, transport, and permanent structural connections.

​Thin Slab Coil Inserts are engineered to provide secure lifting and reliable handling for thin precast concrete panels throughout production, storage, transportation, and installation. Manufactured from high-strength steel with precision-formed coil threads, they deliver excellent load capacity and dependable performance in demanding precast applications.

​Flared Thin Slab Coil Insert is specifically developed for lifting and fixing applications in thin precast concrete components where installation space is limited. Its flared body enhances load distribution within the concrete, while the sealed end prevents concrete slurry from entering the internal thread during casting, ensuring smooth bolt engagement after curing.

​Expanded Coil Coil Inserts are engineered embedded fastening components designed to provide reliable threaded connections and effective load transfer within precast and cast-in-place concrete structures. Featuring an expanded-pitch coil section at the embedded end, the insert distributes applied loads across a larger area of surrounding concrete, helping reduce localized stress concentrations and improve anchoring stability.

Flared Loop Coil Insert is a high-performance embedded fastening component designed for secure threaded connections in precast concrete structures. Manufactured through advanced resistance welding technology, the flared loop connector is firmly welded onto the steel coil to achieve excellent strength, stability, and durability.

The Straight Loop Coil Insert is a reliable embedded fastening component designed to create secure threaded connection points in precast and concrete structures. Its simple loop configuration and efficient fabrication make it suitable for bolted connections, lifting, handling, and anchoring applications when properly engineered.
