Good spring compressors but head bearing washers not included. Also, the casting where the bolt head/bearing washer contacts the attachment "cam” is a raw casting, not a flat casting. It is highly recommended to sand the surface flat/smooth and perpendicular to the hole before use. I understand this is a cheap bottom fed product, but it actually takes less than a minute of machine time to mill a flat surface on a claw. Pull yourself together and get it right the first time! (Also apply anti-seize compound to the screw to avoid damage on first use)
