Contour-following flow lines provideextra shear strength in threads, resiststripping and provide high fatigueresistance.
Extra large root radius doubles fatiguelife compared to flat root thread forms.
Unbrako's controlled runout root radius provides a smooth form that distributes stress and increases fatigue life of thread runout up to 300% for certain sizes.
The sharp angle at the root of con-ventional threads results in high stress concentration and crack initiation points.
Controlled head forging, uniform grain flow and unbroken flow lines, make heads stronger, minimizes failure in vital fillet area, and improves fatigue strength.

Durlok® Free Spinning Self-locking fasteners come with all the benefits of serrated fasteners but with none of the disadvantages. Unlike serrated fasteners, with the unique Durlok® tooth formation, the locking is caused by the elastic spring back of the material at clamping load. A little wall of material builds up behind each tooth thereby blocking the bolt from turning. .
Durlok® is designed with long, ramp shaped, radial teeth blended evenly into a smooth slightly conical outer bearing surface. It is this plain outer bearing ring that prevents excessive penetration into the bearing material, together with the long radial teeth which embed with only moderate edge pressure just sufficient to guarantee self-locking. .
Durlok® Bolts of strength grade 12.9 are manufactured from alloy steel and are through hardened to give the same hardness from the tooth surface to the core. These are typically heavy duty bolts and can be used for all joints subjected to high loads.
The basic design & function of a threaded fastener is to join multi--component assemblies so that the whole assembly performs as a single component. . In most cases, even in preloaded joints, the external forces create minimal relative displacements between the clamped parts, resulting in small sliding movements both in threads and under the head. Thus, the fastener becomes free of friction in a circumferential direction and the internal loosening or “off-torque” created by the preload on the threads will rotate the fastener loose. .
In addition to self-loosening, fatigue failures can occur because the fastener will lose preload as soon as partial loosening takes place.
Durlok® Bolts & Nuts are suitable for multiple re-use because the serrations do not groove the clamped material and maintain locking ability. .
The Durlok® fastener system is effective on a wide variety of engineering materials including steel both heat--treated and non heat-treated, cast irons including nodular types, non--ferrous metals and sheet materials. .
The presence of oil or other lubricants, organic or inorganic coatings will not adversely affect the locking ability. In addition, the corrosion resistance of protected surfaces will generally be maintained because the smooth annular ring of Durlok® fastener shields the bearing area against liquid penetration. .
Durlok® Fasteners can be used at elevated temperatures up to 300°C.

During the 1960's, Dr. Junker while working in Unbrako's Koblenz facility in Germany completed his seminal work on the self-loosening behavior of bolted joints. This in turn led to the design of the original Durlok® anti-vibration nuts & bolts. The Durlok 12.9 nuts & bolts are designed for high-performance critical applications and do not require a washer. However, our industrial OEM customers requested a Durlok product in washer form for applications where it was deemed desirable to use a washer in the joint design. Thus we began researching and developed Unbrako's new Durlok locking wedge washer.
The Durlok® washer when used in combination with standard hex helps achieve self-locking properties. It is an anti-vibration solution that not only prevents bolted joint failure, but also enables the bolted joint to retain its pre-load, thus reducing maintenance requirements. The test regime highlighted this feature (fig 1).

ROLLED THREADS : Rolling threads results in best quality highest-strength thread because of; (1) more accurate and uniformthread dimensions, giving a better fit between threadedparts and fewer concentrated loads at points of misfit;(2) smoother thread surfaces &, thus, fewer scratchesand other markings to initiate cracks, or galling; and(3) higher yield, tensile, & shear properties to betterwithstand service loads.
ECONOMY : Fewer high strength bolts are requiredthan M. S. bolts and rivets. Drilling of close holes isnot required. Overall weight the structure will be verylight.
SIMPLICITY : A minimum of skill is required in tighteningand the operators need only to follow a few simple rules.

TWIST-OFF TYPETENSION CONTROL STRUCTURAL BOLT Tension control structural bolt is an easy to install heavy duty bolt used in steel frame construction. The combination of high tensile strength and ductility results in a structural bolt that can be employed in almost all steel work connections. This high strength positive tension shear bolt has its own built in torque control device.
Unbrako electric shear wrench is used for tightening the bolt. The outer socket rotates the nut until the torque control groove in the spline shears off, thereby achieving proper bolt tension. This shear area is designed to facilitate the ideal seating torque requirements for the installation of the bolt. No specialist operator expertise is required as the correct installation is automatically realized through the design of the bolt.
Installation Procedure:
Unbrako Electric wrenches are available with various socket extensions to match different sizes of Unbrako Tension Control Bolts, allowing easy & accurate installation.

EXTENSION SOCKETS(Step 1)• Place bolt through hole in the joining members. Attach washer & run up nut finger tight to the working members.
(Step 2)• Fit the inner socket of the drive unit firmly over the bolt tip (spline). • Engage the outer socket over the nut by pushing the shear wrench. • Pull lever switch to on. The outer socket rotates the nut. As the tensile load increases the torque tension in the bolt also increases until the bolt reaches its designed shear strength and shears in the designated portion of the bolt.
(Step 3)• Turn off wrench when bolt tip (Spline) shears off.
(Step 4)• Pull the shear wrench back to remove outer socket from the nut. • Pull the eject lever on the wrench to discharge the severed bolt tip (Spline) from the inner socket
• Quick, safe and easy to Install• Speed of Installation.• Visual inspection.• Substantial cost savings.• Consistent Tension is assured in application.• No specialist torque wrenches or gauges required.• No specialist operator expertise required for installation.• Single operator installation & Reduced operator fatigue.
