What Are Locking Pin Backs and Why Use Them
Locking pin backs at Michaels are jewelry fasteners designed to stay closed more securely than basic push-back pins. They typically add a hinged lever, a screw-down collar, or a dual-pin safety mechanism that must be consciously opened, reducing accidental loss. These backs suit pendants, earrings, and lightweight charms where a secure yet easy-to-use closure matters. For beaders and DIY jewelry makers at Michaels, choosing a locking back can improve wearability and customer confidence. This guide covers common types, how to size them, how to attach them, and practical tips so you can select the right locking pin back for each project.
Common Types of Locking Pin Backs at Michaels
M Michaels carries several locking-style backings, each with a different mechanism and best-use case. Understanding these types helps you match the finding to the weight of the piece and how often the item will be put on and taken off.
Spring Locking Back (Lever Back)
A small hinged lever locks over a pin post; pressing the lever down lets you insert the pin, and releasing it snaps the lever back into place. These are faster to open and close than screw backs and suit medium-weight earrings and pendants. They are widely available in precious metal finishes and come in standard sizes such as 15 mm, 20 mm, and 25 mm from the hinge to the pin tip.
Screw-Down Locking Back
A threaded collar screws down over a post behind the pin, creating a secure, low-profile closure. While slower to open, this style offers a firm hold for denser pendants and helps prevent accidental opening. Screw-back lock pins are commonly found in gold- and silver-plated options and are ideal for pieces worn close to the body.
Double-Pointed Pin with Safety Lock
Some lock pins use two points and a tiny safety gate that must be depressed to remove the pin. These are often used on costume and fashion jewelry to provide extra security. They work well on lightweight earrings and flat-backed accessories where a slim profile is preferred over a bulky back.
| Type | Verified Detail | Source Type |
|---|---|---|
| Spring Lock (Lever) | Fast one-hand operation; common in 15–25 mm sizes | Retailer standard offering |
| Screw-Down Lock | Threaded collar for low-profile, secure hold | Retailer standard offering |
| Double-Point Safety Lock | Two-point pin with gate; thin profile for flat backs | Retailer standard offering |
How to Choose the Right Size Locking Pin Back
Pin back size affects comfort, security, and how well the weight of the jewelry is distributed. Too small a back can cause pressure on the skin or allow the piece to tilt; too large a back may feel bulky. At Michaels, backs are commonly measured by the horizontal length of the pin base or the widest point of the locking mechanism, typically in millimeters.
General Sizing Guidelines
- Small (10–14 mm): Lightweight earrings and flat pendants with minimal weight.
- Medium (15–20 mm): Standard earrings and small pendants; suitable for most casual and everyday pieces.
- Large (21–25 mm+): Medium to heavier pendants and statement earrings where a larger surface area helps distribute weight.
When in doubt, choose a back slightly larger than the base of the pendant or the area of earring contact. For heavier materials such as stone or thick metal, prefer a larger locking back or a screw-back style for added security.
How to Attach a Locking Pin Back to Jewelry
Attaching a locking pin back correctly helps ensure the piece stays secure and looks finished. Follow these steps for a sturdy, professional result at home using basic tools from Michaels.
- Gather materials: locking pin back, jewelry component, epoxy or E6000 adhesive, a toothpick or small brush, masking or painter’s tape, and a clean workspace.
- Prepare the surface: wipe the back of the jewelry component with isopropyl alcohol to remove oils and residues that can weaken adhesion.
- Apply adhesive: use a toothpick to place a thin, even layer of jewelry adhesive on the flat contact area of the pin base, avoiding excess that could squeeze out.
- Position the back: align the locking mechanism with the top of the piece (usually the top of the pendant or ear hook area), press firmly, and hold in place.
- Secure while drying: wrap tape around the back and over the pin to maintain even pressure; let cure according to the adhesive instructions, often 12–24 hours for full strength.
- Test: once cured, gently test the lock and the weight of the piece before wearing to confirm it feels secure.
Best Practices and Tips When Using Locking Pin Backs at Michaels
To get the most reliability from your locking pin backs, follow these practical tips. Match the back material to your base metal to reduce skin irritation and tarnish migration. Check that the pin stem is straight and not bent, which can prevent a proper lock. For pieces worn frequently, consider reinforcing with a strong adhesive and taping during cure. Avoid using hot water or harsh cleaners on glued joints, as heat and chemicals can weaken the bond over time. When in doubt, choose a screw-back lock for heavier finds and a lever lock for quicker, everyday use.
Care, Lifespan, and When to Replace Locking Pin Backs
With proper care, locking pin backs can last months to years. Clean jewelry with a soft, damp cloth and dry immediately; avoid soaking glued assemblies. Inspect the lock hinge and screw threads periodically for stiffness or corrosion, especially on plated findings. If the lever feels loose, the pin shows bending, or the adhesive joint cracks, replace the back to prevent loss. Having a few standard sizes on hand at Michaels makes it easy to swap worn findings quickly and keep your jewelry both beautiful and secure.
