Description
Technical Specification & Reference Guide
Component: Needle Clamp Thumb Screw (Part #QM10558)
Product Description
The QM10558 is an OEM, high-tensile needle clamp thumb screw engineered explicitly for industrial-grade quilting platforms. Featuring precision M3 x 6mm threading, its primary mechanical purpose is to exert uniform lateral pressure against the flat shank of high-speed longarm needles (such as the 134 MR series). This component integrates a dual-drive system—a knurled thumb grip for quick manual adjustments and a recessed internal hex-head socket. The hex socket allows operators to apply calibrated torque, completely eliminating the structural vibrations that cause needles to drop, strike the hook assembly, or disrupt hook-to-needle timing profiles during multi-directional, high-velocity stitching.
Overview Section
- OEM Part Number: QM10558 (Also cross-referenced under Baby Lock / Janome partner catalogs)
- Component Type: Dual-Drive (Knurled Thumb + Internal Hex) Needle Clamp Screw
- Thread Pitch/Sizing: M3 x 6mm Standard Metric Machine Thread
- Material Composition: Hardened structural steel alloy with black oxide or polished anti-corrosion finish
- Standard MSRP Range: $5.00 to $7.00 USD
Installation and Placement
Correct installation parameters are vital to safeguard the structural integrity of both the needle bar assembly and the underlying shuttle hook system.
- Spatial Location: Threads directly into the horizontal receiving port on the lower needle bar clamp assembly, situated directly above the hopping foot framework and below the needle bar thread guide.
- Orientation Check: When facing the front control panel of the machine, the screw inserts horizontally from the right-hand side, pushing flush against the flat back-scarf face of the needle shank.
- Required Tooling: Requires a standard 1.5mm / 0.050-inch Allen wrench or specialized longarm hex driver to execute final torque parameters.
- Mechanical Warning: Always utilize manual thumb threading to seat the M3 screw into the aluminum needle bar collar first. Never engage the hex driver immediately, as this significantly increases the risk of cross-threading and stripping the costly lower needle bar assembly.

Authority Troubleshooting Note: If a customer reports chronic thread shredding immediately after replacing this screw, verify that the screw tail is entirely flush inside the clamp. An over-extended or burred screw head can snag the upper thread tail during the rapid up-and-down stroke of the needle bar assembly.
