#6 Hi-Collar Helical Spring Lock Washer gives a socket screw assembly a reduced-OD lock washer made for the space under a socket head cap screw. Its helical form adds resistance to loosening while preserving the counterbore fit expected in socket head cap screw assemblies. Pair this socket head cap screw washer with orders where the counterbore controls washer clearance.
Use this style for equipment with counterbored joints, recessed cap screws, and limited washer clearance when a standard split lock washer has too much outside diameter for the counterbore. Nylon insert socket cap screws provide a different locking approach, with the pellet in the thread instead of spring action under the head.
For hard-to-find socket screw accessories, Cold Headers can help line up the washer size with the matching cap screw requirement. The nominal size matches the screw size; do not size this washer from a broad outside-diameter assumption.
