Heat element welding

HITSERT^® 2

HITSERT^® 2 thread inserts are specially designed for thermal installation. They are available in various versions with nut and bolt threads.

Principle

The HITSERT^® 2 thread insert is heated to the melt temperature of the plastic. Through the heat transfer during insertion, the plastic is briefly plasticised and flows into the undercut and knurling of the thread insert. Cooling then results in a tight fit with low stress..

Benefits

Ideal for thermoplastic parts
Specially designed for thermal installation
Screw-locked and low-tension anchoring
High pull-out values
Efficient installation with single-mandrel, multi-mandrel and automated insertion machinery with preheating device

Ultrasonic welding

SONICSERT^®

SONICSERT^® thread inserts are specially designed for ultrasonic welding. They are available in various versions with nut and bolt threads.

Principle

The SONICSERT^® thread insert is installed using common ultrasonic welding machines. The plastic is plasticised by the ultrasonic vibrations at the welding point and flows into the undercuts of the thread insert. Cooling results in a tight fit with low stress.

Benefits

Suitable for thermoplastic parts
Specially designed for ultrasonic welding
Locked, low-stress anchoring
High pull-out values
Type 0730 can be installed from both sides. Advantageous with automatic feed as no direction-based orientation is necessary here.

Self-tapping insertion

QUICKSERT^®

QUICKSERT^® thread inserts are designed for self-tapping insertion and are available with and without a flange.

Self-tapping insertion

QUICKSERT^®

QUICKSERT^® thread inserts are designed for self-tapping insertion and are available with and without a flange.

Principle

The QUICKSERT^® consists of a cylindrical body with an internal thread and a special external thread. The external thread profile has an extremely small flank angle and increases asymmetrically to the root of the thread. This optimises installation with low driving torques. Very good tight fit is achieved with an ideal distribution of load. The lower part of the bush is provided with a cutting slot. The thread bush is screwed in with a rotating spindle.

Benefits

For brittle and ductile plastics, e.g. unsaturated polyester resins (SMC, ZMC), polyurethane and glass fibre-reinforced thermoplastics
Universal application
High-strength, torsion-proof threads
Optimum assembly characteristics

QUICKSERT^® Hex

QUICKSERT^® Hex thread inserts are designed for self-tapping insertion and are available with and without a flange.

Self-tapping insertion

QUICKSERT^® Hex

QUICKSERT^® Hex thread inserts are designed for self-tapping insertion and are available with and without a flange.

Principle

The QUICKSERT^® Hex consists of a cylindrical body with an inner thread, internal hexagon and a special external thread. The external thread profile has an extremely small flank angle and expands asymmetrically to the thread root. Assembly is thus optimised with low screw-in torques. With ideal load distribution, a tight fit is ensured. The bottom part of the bush has a cutting slot. The thread bush is inserted and screwed in with a rotating spindle, which does not have to be screwed out.

Benefits

Efficient installation process due to additional drive feature (e.g. internal hexagon).
For thermoplastic and thermoset materials
Radial stresses minimised by extra-small flank angle of special external thread
High-strength and torsion-proof threads
Special version available with external left-hand thread for improved resistance to unscrewing

Self-forming insertion

QUICKSERT^® Plus

QUICKSERT^® Plus thread inserts are designed for self-forming insertion and are available with and without a flange.

Self-forming insertion

QUICKSERT^® Plus

QUICKSERT^® Plus thread inserts are designed for self-forming insertion and are available with and without a flange.

Principle

The QUICKSERT^® Plus consists of a tapering body (overall taper 8°) with an internal thread, additional internal hexagon and a special external thread. The external thread profile has an extremely small flank angle and increases asymmetrically to the root of the thread. Driving torques for installation are thus reduced. With ideal load distribution, a tight fit is ensured. Since no cutting slot is needed, no chip is produced because the thread insert moulds itself into the plastic. The thread bush is inserted and screwed in with a rotating spindle.

Benefits

Suitable for thermoplastic parts
High-strength, torsion-proof threads
Chipless installation
Special version available with external left-hand thread for improved reverse locking

SPREDSERT^® 1

SPREDSERT^® 1 thread inserts are designed for expansion anchoring with thermoplastic parts.

Principle

The SPREDSERT^® 1 is inserted into the bore hole until the knurled collar is fully anchored in the plastic. The slotted section is compressed at the same time. The screw causes the radially secured SPREDSERT^® 2 to expand again, the anchor rings penetrate the plastic material and ensure the tight fit of the thread insert. The screw is additionally locked in the process. For the additional expansion force, it is necessary to increase the tightening torque by 10%.

Benefits

For thermoplastic parts
The knurled collar and anchor rings offer a high level of security against twisting and tensile load
Screw locking

Expansion anchoring

SPREDSERT^® with retaining flange

SPREDSERT^® thread inserts with a retaining flange are designed for expansion anchoring with thermoset and thermoplastic parts.

Principle

The SPREDSERT^® with retaining flange is inserted into the through hole at the rear until the retaining flange is seated. The slotted anchoring section with diamond knurl is compressed.
By screwing in the screw, the thread insert is pushed apart in the anchoring section, so that the diamond knurling penetrates the plastic material. Acting as a shoulder support, the retaining flange prevents pull-out.
The screw is also locked at the same time. For the additional expansion force, the tightening torque must be increased by 10 %.

Benefits

For thermoset and thermoplastic parts
High-strength threads in through holes

Expansion anchoring

QUICKSERT^® Expansion

QUICKSERT^® Expansion type 1230 thread inserts are designed for expansion anchoring with thermoset and thermoplastic parts.

Principle

The QUICKSERT^® Expansion is spun on to the rotating threaded mandrel of the installation tool and introduced into the mounting hole. This hole may be preformed or created as a blind or through hole using a standard drill. The axial pulling action of the mandrel makes the QUICKSERT^® Expansion shear at the predetermined breaking point between the anchoring sleeve and thread bush. The bush is drawn into the anchoring sleeve and expands it. Meanwhile, the diamond knurling of the anchoring sleeve is pressed into the wall of the hole. The thread insert is now securely anchored to prevent twisting or pull-out.
