Inner Screw

When a mechanical traction frame starts to feel shaky, loose, or out of alignment, the issue is almost always a worn-out or missing fastener deeper inside the assembly. Because a traction device operates under constant spring-back counter-pressure, every single tiny screw is structural. If an internal fastener falls out during a routine cleaning, rolls away, or gets its fine threads stripped after months of tightening, your device loses its stable frame calibration, making it unsafe or impossible to wear.

Whether you call it a traction device internal pin, a replacement mini machine screw, or a calibration assembly fastener, this genuine Inner Screw is the precise manufacturer hardware spare required to lock your device securely back together.

As you can see in image this direct manufacturer component is a high-grade, short metal machine screw featuring a pan-head drive and clean, heavy-duty tracking threads. It is purposefully engineered to sit flush inside the mechanical core of your ProExtender device, ensuring that your side calibration tubes or adjustment dials stay perfectly anchored without slipping.

Real Structural Problems This Replacement Screw Solves:

• Loose or Wobbly Frame Tubes: If your side bars wiggle or rattle even when you think you have tightened the device completely, an internal locking screw has backed out or gone missing. Installing this fresh factory screw locks the core structural alignment completely solid.

• Stripped, Cross-Threaded Fasteners: Because these small screws handle the brunt of the tension force from the internal springs, the metal threads can eventually wear smooth or cross-thread during adjustments. The crisp, deep threads ensure a rock-solid, non-slip mechanical grip.

• Lost Hardware During Maintenance: To properly clean your traction system and prevent bacterial buildup, the framework needs to be taken apart completely from time to time. Because this internal fastener is so tiny, it can easily drop down a sink drain or get lost in a dark carpet. This direct-match spare ensures you don’t have to shelve your routine.

• Eliminating Shifting Calibration: If your tension adjustment bars slip backwards mid-session, the inner locking mechanics lack the necessary friction. A brand-new inner screw securely clamps the internal hardware components right where they need to be.

The “Inner Screw Hardware” FAQ

Solving Your Mechanical & Repair Questions

Q: Where exactly does the Inner Screw go inside the device?

A: This screw is an internal mechanical anchor point for the ProExtender system. It typically acts as the primary fastener that secures the inner spring rod bars, the lower calibration tubes, or the spindle adjustment plates to the main structural frame.

Q: What tools do I need to install this replacement screw?

A: As shown in image, this component features a standard cross/slot combination head drive. You will only need a basic, small household screwdriver (such as a precision Phillips or flathead screwdriver) to smoothly tighten it into place inside your device frame.

Q: How can I prevent these small internal screws from stripping or backing out?

A: Always tighten the screw firmly by hand until it sits flush and resists turning, but never force or over-tighten it past its stopping point, as excessive force can strip out the fine metal threads. Additionally, make sure the internal socket is completely dry before screwing it in to prevent any trapped moisture from causing resistance.

Q: Is the shipping box completely private?

A: 100% private, without exception. At My Novelty Shop, your absolute discretion is our highest priority. Your order will be packed inside an entirely plain, unmarked courier envelope or a standard brown cardboard box. There are zero store logos, no references to personal wellness or intimate systems, and no product descriptions anywhere on the outside shipping label. It looks completely identical to a routine delivery of everyday household hardware, machine screws, or small electronic replacement parts.
