Linear Headset Press Service Tool

BRT-058 - Linear Headset Press Kit with Guides and Zipnut - - designed for installation of all sizes of headset cups. This kit includes 3/8 inch (10mm) Acme thread press rod sized for headset installation, a pair of interchangeable Liner Quick Handles, a quick-action 3/8 Zipnut, and a full complement of guides to ensure efficient and accurate headset installation. The Linear Headset Press utilizes the same 29 degree angle Acme thread design found in high precision applications such lead screw drives for CNC machines. This design results in wider and broader thread bases which have greater strength and overall durability. Most importantly, this thread design is much more accurate than standard V shaped threads providing exact 90 degree force for perfect bearing seating and installation alignment. Unlike other bearing press products available which specify a plain bushing or no bearing at all, each Linear Press rod features a static nut fitted with a precision thrust bearing to provide smooth and accurate, bind-free action. Finally, the Linear Quick handles are like small transformers where you can combine two short handles for tight spaces, two longer handles for more leverage or long-short handles for control. These 6061 alloy handles snap on to the fixed thrust nut and our unique quick-action Zipnut, for quick, professional results. Drive them by hand, or with open-end or socket wrenches, or if one prefers to work with Allen wrenches, that option has been machined into the end of each handle as well.
