Here are the models, thread types, load groups and other information of various types of Precast Lifting Thread Inserts. You can click to jump to the corresponding product details to learn more. You can also contact us directly to get a quote.
| Lifting Insert Type | What It Is | How It Works | Typical Applications |
|---|---|---|---|
| Flat End Lifting Insert | A straight-threaded insert with a flat end, embedded in precast concrete for lifting. | Cast into concrete with the threaded end exposed; a lifting loop or clutch screws into the thread to transfer the load. | Lifting flat panels, beams, and slabs where minimal protrusion is needed. |
| Solid Rod Lifting & Fixing Socket | A robust lifting socket made from a solid steel rod with a threaded hole. | Embedded with reinforcement; engages with lifting equipment to transfer heavy loads safely. | Heavy precast elements, structural beams, columns, and connection fixing points. |
| Combi Lifting Socket | A multi-purpose threaded insert combining lifting and fixing functions. | Works with both lifting clutches and bolts; allows the same insert to be used for handling and installation. | Precast wall panels, façade units, and elements requiring post-installation fixing. |
| Tubular Lifting Insert | A lifting insert made from thick-walled steel tube with an internal thread. | The tube’s length provides strong anchorage; lifting loops or clutches engage with the thread to lift. | Thick precast elements, large blocks, and heavy industrial components. |
| Wavy Tail Lifting Insert | A threaded insert with a wavy steel tail for better anchorage in concrete. | The wavy tail locks into the concrete mass, distributing forces during lifting. | Thin panels, stairs, and elements with limited concrete cover. |
| Crown Foot Lifting Anchor | A forged steel anchor with a widened crown base for high load capacity. | The crown base spreads the load into the concrete; used with matching lifting clutches. | Heavy-duty lifting of walls, beams, and large structural precast units. |
| Bolt Anchor Lifting Sockets | Threaded sockets designed to work with bolts or lifting eyes for both lifting and fixing. | Bolts or threaded rods connect directly for lifting or securing in place. | Precast components needing both lifting and permanent bolted connections. |
The production of Precast lifting thread insert needs to be described according to different styles. Therefore, only some general production processes are introduced here. You can click the related products below to learn more.
Raw materials come from our close cooperative suppliers. They need to pass strict sampling inspection before they are used in the production of Precast lifting thread insert. We have advanced testing instruments to complete the sampling inspection of various indicators to ensure that the quality of the raw materials meets the requirements.
The raw materials are cut into specific lengths and shapes for the next step of production. During this process, our quality inspectors will randomly check the size of the blanks to ensure that the tolerance meets the requirements of the next link:
Precast lifting thread inserts with different functions will use specific processes to complete the final forming work:
Put the steel pipe into the mold, squeeze the other end, and then punch out the hole, and finally tap it to complete the production.
Drill one end of the solid steel rod and tap the other end.
Drill one end of the steel pipe and tap the other end.
after the rebar is bent into a specific shape, one end of the steel pipe is fixed to the rebar by extrusion and the other end of the steel pipe is tapped.
the process is the same as Wavy Insert, the difference is that steel rods are used instead of threaded steel.
weld the tapped steel pipe to the steel plate. Most of the steel plates are square.
screw a long bolt into the tapped threaded pipe, and use a special mold to make a mark on the connection between the steel pipe and the bolt to prevent the screw from turning further.
The stainless steel precast lifting thread insert has strong corrosion resistance, while the steel one needs surface treatment: dip coating with anti-rust oil, hot-dip galvanizing or electro-galvanizing.
We support customization of packaging materials and appearance. You can provide the outer packaging group, and we can provide spraying and printing services.
We have close cooperation with express, sea, air and land transportation companies to find a more suitable transportation method to deliver the goods to you faster and safely.

In order to provide higher quality precast lifting thread insert, we have formulated strict sampling standards to ensure that the samples are more representative. We will issue a complete quality inspection report for each order.
We strictly test the thread, thread depth, hole diameter, etc. to ensure that the tolerance meets the requirements.
We randomly sample and perform tensile tests. The sample of precast lifting thread insert must be tested under a tensile force of 3 times the safety factor to be qualified.
We have detailed unit weights and use the weighing and counting method to accurately calculate the quantity of each batch of goods. If the goods are short after receipt, we can negotiate to resend.
We will unpack and reinspect the size, quantity, and packaging of the precast lifting thread insert before shipment.
