Description of the marine-grade stainless steel ball stud bracket Ø10 mm – EFBR13S
The EFBR13S marine-grade stainless steel ball stud bracket Ø10 mm is the fixing interface between a gas spring and the structure of your boat. It accepts every AS Raymond / Ressorts SPEC gas strut equipped with a 10 mm ball socket, and secures it to a bulkhead, a hatch frame, a locker lid or a cabinet side with three screws (not supplied).
This ball mount flange combines a round base plate, Ø28 mm across and only 2 mm thick, with a Ø10 mm ball stud. Total projection from the mounting surface is just 14.5 mm. The low profile suits the tight clearances found around hatches, engine-room access panels, bench seats and saloon furniture. The three Ø4.0 mm holes sit on a Ø20.9 mm pitch circle at 120°, which spreads the load evenly around the ball stud.
On a marine installation, the fixing point is often what fails first. Moisture, spray and salt air quickly attack zinc-plated hardware. A marine-grade stainless steel bracket keeps its mechanical integrity and appearance over time, whether it is fitted inside a cockpit locker, on a sunbed lid or on an anchor-locker hatch. Its polished finish also blends in with the stainless deck hardware already found on most yachts.
The ball-joint principle lets the gas spring articulate freely through the opening arc of the panel. Ball sockets clip onto the ball stud without tools, so a worn gas strut can be replaced in seconds without touching the bracket. For shipyards and refit professionals, the EFBR13S is a standard part that simplifies the bill of materials across many applications aboard leisure boats, motor yachts, sailing yachts and work boats.

Installation / Maintenance
Installation:
- Mark the three holes using the bracket itself as a template, on the Ø20.9 mm pitch circle.
- Fasten the EFBR13S to a rigid support (bulkhead, frame, reinforcement pad). On thin GRP or plywood panels, add a backing plate to distribute the load.
- Use stainless steel screws (A4 recommended) suited to Ø4.0 mm holes, to avoid galvanic corrosion between dissimilar metals.
- Position the bracket so the gas spring works in line with the ball stud throughout the opening arc, without side loading.
Maintenance:
- Rinse with fresh water periodically, especially on exterior or deck installations.
- Check screw tightness and the condition of the ball socket during routine boat maintenance.
Our review
✔️ Pros :
- Marine-grade stainless steel, suited to the nautical environment.
- Compact, low-profile design (14.5 mm projection).
- Three-point fixing at 120° for an even load distribution.
- Fits all AS Raymond / Ressorts SPEC gas springs with Ø10 mm ball sockets.
- Tool-free gas strut replacement thanks to the ball-joint connection.
❌ Cons :
- Fixing screws not supplied.
- Only compatible with 10 mm ball sockets (not 13 mm).
- Small Ø4.0 mm holes: a rigid support is essential for high-force gas springs.
Conclusion
The EFBR13S is the right choice if you need a durable, discreet anchor point for a gas spring fitted with a Ø10 mm ball socket. Its marine-grade stainless steel construction makes it well suited to nautical use, both inside and on deck. Before ordering, check that your gas strut uses a 10 mm ball socket, such as the EFBS006S, EFBS002S or EFBS004P, and that the support is stiff enough for the spring force. If the round flange does not suit your mounting surface, the EFBR12S, EFBR07S or EFBR02S brackets offer other fixing options with the same Ø10 mm ball.
Good to Know
- Sold without screws – plan for stainless steel fasteners matching Ø4.0 mm holes.
- One bracket per gas spring end: order two if both ends require a ball stud.
- Works with our Ø10 mm ball sockets EFBS006S, EFBS002S and EFBS004P.
- Browse our full range of gas springs for boats to find the matching strut.
