BODY
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 Bolt & Nut
2 Pairs of Durlok Washers

No Washer
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).
®Durlok Nut
lt® oB kolruD
Reusability is guaranteed with locking ability maintained.
Will not loosen or unscrew even under the most severe transverse jarring and vibration.
Effectiveness at elevated temperatures upto 300° C is ensured.
Unique head design ensures absence of ‘notch-effect’
after assembly
Embedding is no greater than with standard types of fasteners.
Closely controlled manufacturing for
extra safety and reliability.

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.
