The Linear 2400-183 is an OEM spare part for a wide range of Linear and OSCO gate operator models. This carriage bolt measures 3/8-16 UNC thread x 1 in. length, round domed head with square neck and is made of carbon steel (zinc plated or plain finish). It installs by through clearance hole with square neck engaged in material, nut tightened from opposite side. Using genuine Linear replacement hardware ensures proper fit and reliable operation of your gate operator.
