MECHANICS
Industrial machinery and mechanics require reliable and tailored bolts. We offer customized solutions to ensure safety and efficiency in every project.
We provide special bolts for the mechanics and machinery sector, focusing on machine tools intended for operation-intensive industries. Examples include: paper industry, cement factories, automotive, food industry and packaging.
One of the most technical areas is laminar joints, used to ensure perfect alignment between rotating shafts or coupled mechanical components. These joints are designed to reduce vibration and torsional stresses during operation. In order to ensure stability and durability they require very high precision fasteners that can withstand high dynamic loads and cyclic stresses.
EFS manufactures custom screws, pins and studs for all kinds of mechanical applications, even with dedicated surface treatments.
