Agilent, 0515-0850, Screw-Skt-Hd-Cap-M4X0.7-40mm-Lg

The Agilent Socket-Head Cap Screw is a metric mechanical fastener with an M4 thread, 0.7 mm thread pitch and 40 mm length. It is used at specified fastening positions in compatible Agilent instrument assemblies, including analytical autosampler head mechanisms. Correct screw geometry is important for maintaining component alignment and clamping without damaging machined parts. During servicing, confirm that the existing fastener uses the same thread diameter, pitch, length and head style before replacement. Insert the screw into clean threads and apply the instrument's specified fastening procedure rather than assuming that a similar-looking metric bolt is interchangeable. Incorrect screw length can interfere with adjacent moving parts or fail to secure the assembly correctly. Inspect mating threads if the original fastener was damaged or loosened repeatedly. This item is a socket-head machine screw, not a pump piston, injection syringe, autosampler head or full service kit. Package quantity must be confirmed separately from its dimensional specification.
