The Makita 231934-8 Spiral Spring is a genuine OEM replacement part designed to restore reliable return tension in selected Makita circular and mitre saws, including the BLS713 and BLS820. Constructed from tough, tempered spring steel in a flat, coiled configuration with hooked ends, this spring seats securely within original housings to deliver consistent tension to guards or linkages during operation. Its durable construction resists fatigue and deformation, supporting long-term serviceability under regular use. Replacing a worn, fatigued, or broken spring with this genuine Makita part helps maintain smooth tool operation, consistent guard return, and accurate performance — all critical factors on a busy job site. As a direct like-for-like replacement using Makita's own Manufacturer Part Number 231934-8, it eliminates the guesswork and fitment issues that can come with non-OEM alternatives.
