These double-ended snap hooks are seriously versatile - you'll find uses for them everywhere! Made from heavy-duty brass that stands up to saltwater and outdoor conditions without rusting. The 96mm (3.77 inch) size is perfect for multiple applications, and the spring-loaded bolts provide secure closure while still being easy to open with one hand. The double-ended design means you can connect chains, ropes, or straps on both ends, making them super flexible for different setups. Perfect for marine use like diving gear, dog leashes and training equipment, horse tack, key chains, or general hardware applications around the house or farm. The thumb lever moves smoothly and the construction feels solid - no cheap, flimsy hardware here. Each package includes 2 snaps, so you can use them for multiple projects. Just remember they're not for climbing or heavy load-bearing safety applications. If the mechanism feels stiff initially, a little lubricating oil solves that quickly. Whether you're organizing gear on your boat, creating custom dog leashes, or need reliable hardware for outdoor equipment, these brass snaps deliver quality and functionality that holds up through regular use.
