FAQs
What is the 114511003 screw used for?
The 114511003 is a fixing screw used for compatible industrial sewing machine bobbin winder assemblies. It secures the bobbin winder or related mounting component to the machine structure. The supplied specification identifies it as an SM11/64-28 screw with a 10 mm length.
What is the thread size of 114511003?
The specified thread is SM11/64-28, with a 10 mm length. Thread size is important when replacing a machine screw because a screw with a different thread pitch or diameter may not engage correctly and can damage the threaded mounting hole.
Does this screw fit Jack JK-9100?
Yes. The supplied compatibility information lists the Jack JK-9100 among the compatible machines. It is also specified for Jack JK-A2, JK-A3, JK-A4, JK-A5, and F4 industrial single-needle lockstitch machines.
Is this only for Jack sewing machines?
No. The supplied compatibility information also lists compatible bobbin-winder applications from Juki, Singer, Brother, Siruba, and Zoje. However, compatibility depends on the actual bobbin-winder mounting arrangement and thread specification, so the existing screw should be compared before ordering.
What should I check before buying this screw?
Check the existing screw’s thread specification, length, head style, and mounting application. For this product, the supplied specification is SM11/64-28 with a 10 mm length. Matching these details is more reliable than selecting a screw based only on the machine brand.
Can this screw be used for other parts of a sewing machine?
It should be used for applications where the specified thread and dimensions match. This product is identified specifically as a bobbin winder fixing screw. Using it elsewhere without confirming the thread, length, clearance, and mounting requirements can result in an incorrect fit.
Is the screw suitable for industrial sewing machines?
Yes. It is specified for industrial single-needle lockstitch bobbin-winder assemblies. The hardened carbon-steel construction is intended for mechanical fastening applications where the screw is exposed to regular vibration, maintenance, and repeated machine operation.
Does the screw come with a bobbin winder?
No. The listing is for 1 piece of the fixing screw only. The bobbin winder, bracket, machine head, and other mounting components are not included unless separately stated in the product listing.
How do I install the 114511003 screw?
First, switch off the machine. Next, align the bobbin winder or mounting bracket with its threaded mounting point. Then, insert the screw and tighten it with a suitable screwdriver. Finally, check that the bobbin winder remains properly aligned and rotates or operates freely before production use.
Can I replace a missing bobbin-winder screw with this part?
Yes, when the original application requires the specified SM11/64-28, 10 mm screw configuration. Confirm the thread and length of the missing screw’s mounting position before ordering because visually similar sewing-machine screws can have different thread specifications.
What happens if the wrong thread is used?
A screw with an incorrect thread can fail to engage properly, loosen during machine operation, or damage the threaded mounting point. The correct diameter and thread pitch are therefore important. For this part, verify the SM11/64-28 specification before installation.
Is this screw corrosion resistant?
The supplied product specification states that the screw has a protective anti-rust finish intended to resist oxidation and exposure to sewing-machine oil and workshop conditions. Keeping the screw and surrounding mounting area clean also helps maintain the fastening connection.
