Ellora Group is proud to be the authorised distributor for UNBRAKO bolts and nuts in Qatar. UNBRAKO is the world leader in fasteners and we are pleased to offer their high quality and certified products to our customers.
Among the UNBRAKO products most in demand are socket screws. Let's take a look at why this is so.
The most important reasons for the increasing use of socket head cap screws in industry are safety, reliability and economy. All three reasons are directly traceable to the superior performance of socket screws vs. other fasteners due to their superior strength and advanced design.
Reliability, higher pressures, stresses and speeds in todays machines and equipment demand stronger, more reliable fasteners to hold them together.
Rising costs make failure and downtime intolerable. Bigger, more complex units break down more frequently despite every effort to prevent it.
This is why the reliability of every component has become critical. Components must stay together to function properly, and to keep them together joints must stay tight.
UNBRAKO developed the first internal hex socket screw and is the world's leading socket screw brand with more than 100 years' experience of supplying to the high-end industries, such as the automotive, infrastructure, aerospace, petrochemical, heavy machinery and military sectors.
UNBRAKO socket cap screws offer joint reliability, safety with maximum strength and fatigue resistance greater than any other threaded fastener.
UNBRAKO12.9 metric alloy steel socket head cap screws are manufactured to strength levels of 1300/1250 MPa (depending on dia) compared to the industry standard of 1220 MPa. For inch sizes, UNBRAKO manufactures to 190/180 Ksi compared to the industry standard per ASTM A574 of 180/170 Ksi.
This higher tensile strength can be translated into savings. Fewer socket screws of the same size can be used to achieve the same clamping force in the joint. A joint requiring 12 x 1-3/8” Grade 5 hex heads would need only 7 UNBRAKO socket head cap screws. Thus, there are fewer holes to drill & tap, fewer screws to buy & handle. Using smaller diameter socket head cap screws vs. larger hex screws costs less to drill and tap, need less space, require no additional wrench space, take less energy to drive, and there is also weight saving.
Joints that are subject to external stress loading are susceptible to fatigue failure. UNBRAKO socket screws have distinct advantages that give you an extra bonus of protection against this hazard, namely - design improvements, mechanical properties & closely controlled manufacturing processes.
