The Linear 2400-407 is an OEM replacement brass-tip set screw from the Linear 2400-series parts catalog. It measures 5/16-18 thread, 5/16 in length. Constructed from Alloy steel body with brass tip insert. 5/16-18 UNC coarse thread for positive engagement in hub or collar. 5/16 in length - compact for thin-hub applications. Brass tip protects precision shaft from damage during tightening. Compatible with Linear SWG series gate operators and Linear SG series gate operators among other Linear gate operator series.
A: It is a 5/16-18 x 5/16 in set screw with a soft brass tip that contacts the shaft, preventing damage to precision shaft surfaces during tightening.
A: The brass tip is softer than the steel shaft, so it deforms rather than gouging the shaft when the set screw is torqued down, preserving shaft integrity.
A: It is used in drive shaft and hub assemblies within Linear gate operator gear and motor assemblies where precise shaft locking without surface damage is required.
A: The 5/16-18 thread engages the tapped hole in a hub or collar, and tightening drives the brass tip firmly against the shaft to lock rotational position.
A: Use an Allen hex key of the correct size for the socket drive recess. Do not overtighten - apply specified torque to avoid deforming the brass tip excessively.
