Advantages of HSFG Bolts

•HSFG bolts do not allow any slip between the elements connected, especially in close tolerance holes, Thus they provide rigid connections.
• Because of the clamping action, load is transmitted by friction only and the bolts are not subjected to shear and bearing.
• Due to the smaller number of bolts, the gusset plate sizes are reduced.
• Deformation is minimized.
• Holes larger than usual can be provided to ease erection and take care of lack-of-fit. However note that the type of hole will govern the strength of the connection.
• Noiseless fabrication, since the bolts are tightened with wrenches.
• The possibility of failure at the net section under the working loads is eliminated.

Since the loads causing fatigue will be within proof load, the nuts are prevented from loosening and the fatigue strength of the joint will be greater than in welded/connections.
• Since the load is transferred by friction, there is no stress concentration in the holes.
• Unlike riveted joints, few persons are required for making the connections.
• No heating is required and no danger of tossing of bolt. Thus safety of the workers is enhanced.
• Alterations, if any (e.g. replacement of defective bolt) is done easily than in welded connections.

HILTI ANCHOR ROD

* BB Saha & Sons, offers Hilti Anchor Rods and elements in 4.8, 5.8, and 8.8 grades. The first digit of the grade refers to the material’s ultimate tensile strength, and the second digit is the ratio of yield stress to ultimate stress. For example, 5.8 grade steel has an ultimate tensile strength of 500 N/mm2 and a yield stress of 400 N/mm2 (500 x 0.8 = 400 N/mm2).
* All Hilti threaded anchor rods are as per ISO 898 standard. Hilti has 4.8, 5.8 and 8.8 grade threaded anchor rods in the Indian Portfolio.
