Cold Bent U-Bolts
cold bent u-bolts are made from ground alloy steel bright bars having a uts of 80-95 kg/mm2. These u bolts are cold formed and
hence the need for post bending heat treatment is eliminated. On the other hand, the bends in a hot bent u bolt become weak as the steel at the bends gets normalized due to heating and subsequent air cooling. Thus there exists a uts gradient at the bends. concentration of stress also occurs at the bends due to change of shape of cross section.
a combination of uts gradient and stress concentration at the bends makes the hot bent u bolt susceptible to failure under dynamic loading.
in order to regain the strength of the parent material and to relieve stresses, heat treatment of the u bolt is required. This leads to: 1. Increase in cost
2. Decarburisation and hence softening of threads if the furnace atmosphere is not completely inert.

About the Company
Engineering Enterprises was started in 1995 by a team of mechanical engineers having substantial work experience in automobile industry. The partnership firm was established as OEM to manufacture and supply U Bolts for various heavy and Light commercial vehicles manufactured by TELCO. TELCO is India's premier truck and multi utility vehicle manufacturing company.
Since then the company has diversified into manufacturing and supplying U Bolts for the domestic aftermarket. U Boltdimensions viz. thread parameters, length and shank diameter are dictated by the market requirements. Other quality and metallurgical parametersincluding raw material grade are as per EE's very stringent quality norms.
Besides U Bolts EE also supplies other components involving thread rolling & Zinc plating as original equipment to Telco.
