#5 Hi-Collar Helical Spring Lock Washer is a hi-collar helical spring lock washer for socket head cap screw counterbores and compact recessed joints. The taller section and smaller outside diameter distinguish it from a standard split washer while maintaining spring action under the cap screw head. Order it with the matching socket head cap screws so the screw and washer sizes stay aligned.
Typical applications include die and fixture builds, jig plates, toolroom repairs, and guided machine details, where washer clearance under the socket head is part of the design. For a locking approach built into the screw itself, compare 1960 Series Alloy SHCS with Nylon Insert. Review 18-8 Stainless Socket Head Cap Screws when the screw material requirement changes.
Cold Headers helps maintenance teams and distributors match the small companion parts that keep socket screw orders complete. Review the cap screw size, counterbore diameter, joint stack-up, and washer style before substituting a standard split washer.
