YASI Single Ended Boltsnap

YASI single ended boltsnap

Good clip hardware is easy to overlook until it lets you down. The YASI single-ended boltsnap is 316 stainless steel throughout, spring-loaded, and built to work reliably whether you're clipping off an SPG in cold UK waters or rigging stage bottles for a longer penetration dive.

It comes in two lengths: 84mm for lighter, more compact clip points, and 110mm where you need a bit more reach or are working with bulkier D-ring configurations. The 15mm gate opening handles standard diving hardware without fuss.

• Material: 316 stainless steel
• Gate opening: 15mm
• Design: Single-ended, spring-loaded gate
• Available lengths: 84mm and 110mm
• Finish: Polished, corrosion-resistant

Why divers choose this boltsnap

One-handed operation when your other hand is busy

At depth, your hands are rarely free. Whether you're holding a torch, managing a guideline, or keeping station in current, clip hardware that needs two hands to operate is a liability. The YASI single-ended boltsnap opens and closes with one hand, cleanly, without the gate sticking or the snap rotating in your grip.

316 stainless holds up where cheaper hardware corrodes

Standard stainless will pit and seize after sustained saltwater exposure. 316 grade resists chloride corrosion better, which is why it's the material of choice for marine hardware. We've seen cheaper boltsnapps from unknown brands start showing rust and stiffening gates within a season. This one won't.

A size for every clip point

The 84mm version works well for SPG clips, torch fittings, and secondary accessory points where a shorter snap sits tidier. The 110mm is the better choice for stage bottle clips, buoy lines, and anywhere you want more mechanical advantage when working gloved. Having both available means you can match the snap to the job rather than making do.

Features that matter underwater

Spring-loaded gate

The gate returns under spring tension, so it stays closed under load and won't unclip accidentally if another piece of kit snags it. This is the standard you should expect from any clip used in technical or overhead diving.

Single-ended design

The fixed end attaches permanently to your harness D-ring, BCD attachment point, or line. The single open gate is where you clip and unclip gear. This simplifies operation and reduces the chance of accidentally releasing the wrong end under stress, which matters in overhead environments.

Polished finish

The polished surface resists salt build-up and makes the gate easier to inspect for corrosion or wear between dives. It also makes the snap easier to wipe down after saltwater use, which adds up if you're diving regularly.

Why choose the YASI boltsnap

There are plenty of boltsnapps on the market, from generic marine hardware to higher-end technical diving brands. The YASI sits in solid mid-range territory: proper 316 stainless construction, a clean gate action, and two size options that cover most diving configurations. It's not the cheapest clip you'll find, but it's the kind of hardware that won't surprise you underwater.

If you're building out a technical rig from scratch or replacing worn clip hardware across a sidemount setup, these are a sensible choice. They work equally well as primary harness clips, backup reg tethers, and accessory points. For recreational divers who want one reliable clip for a torch or SMB, the 84mm version is the one to go for.

Who is this boltsnap for

• Technical and sidemount divers building or upgrading their harness configuration
• Cave and wreck divers who need reliable, one-handed clip hardware
• Recreational divers wanting a proper stainless snap for torches, SMBs, or accessory clips
• Instructors and dive professionals who go through clip hardware regularly

Who it may not be for: if you need a double-ended snap for clipping between two D-rings, take a look at the XDEEP double-ended boltsnap instead. For other hardware options, browse our full accessories collection.

How to get the best from this boltsnap

Boltsnapps are simple hardware, but how you rig them matters. A poorly positioned clip creates drag, tangles, or ends up somewhere you can't reach it when you need it.

• Thread the fixed end through your D-ring or harness attachment point before your dive, not on the surface as an afterthought.
• Position the snap so the gate faces away from your body and opens outward. This makes one-handed operation more natural and reduces snagging.
• Rinse with fresh water after every saltwater dive. Work the gate open and closed several times while rinsing to flush salt from the spring mechanism.
• Check spring tension regularly. A weak or sticky gate is a sign the snap needs replacing before your next dive.
