40PCS Metal Locking Pin Back Clasps for Brooch Enamel Lapel Pins
40PCS Metal Locking Pin Back Clasps — Secure Nickel-Plated Pin Backs for Enamel & Lapel Pins
Protect your pins with confidence. These nickel-plated copper locking pin backs feature a spring-loaded latch and a snap design that keeps enamel pins, lapel pins, badges, and brooches firmly in place.
Why choose locking pin backs?
Traditional friction pin backs can loosen over time and lead to lost or damaged pins. Locking pin back clasps add a mechanical layer of security — the spring-loaded latch locks into place and resists accidental removal, making them ideal for valuable or frequently-worn pins.
Product Features
- Quality Material: Durable nickel-plated copper for corrosion resistance and long-lasting use.
- Easy to Use: Spring-loaded latch design for effortless locking and removal — no tools required.
- Secure Your Pins: Unique snap design prevents pins from falling off or getting lost.
- Widely Used: Compatible with enamel pins, lapel pins, brooches, name tags, lanyards, bags, hats, jean buttons, and display books.
- Value Pack: Includes 40 locking pin backs. Dimensions: 0.4 inch (diameter) × 0.25 inch (height), compatible with most standard pin sizes.
Benefits & Use Cases
Whether you run an enamel pin store, produce custom lapel pins for events, or collect pins as a hobby, these locking pin backs provide peace of mind. Use them when:
- You ship pins to customers and want fewer returns due to lost backs;
- You display pins on fabric where movement occurs (bags, hats, jackets);
- You want a tidy, professional look at trade shows, conferences, and events;
- You’re creating DIY pin kits and need consistent, easy-to-install hardware.
How to install and care for locking pin backs
- Push the pin post through the fabric or material.
- Align the locking pin back with the post and press until it clicks into place.
- To remove, press the small latch and pull the back away from the post.
To maximize lifespan, avoid prolonged exposure to moisture and wipe with a soft cloth if needed. Nickel-plating resists rust, but careful handling will keep clasps looking new.
Frequently Asked Questions (FAQ)
Are these compatible with all enamel pins?
They are compatible with most standard pin posts (0.4 in diameter and typical post thickness). If you have an unusually thick or thin post, test one clasp before using the entire pack.
Can I use them on thick fabrics?
They work best on single- to medium-thickness fabrics. For very thick materials (heavy-duty denim, multiple layers), confirm fit — you may need longer posts or specialty backs.
