Sta-Lok Bronze Turnbuckles

Sta-Lok Bronze Turnbuckles

Sta-Lok Bronze Turnbuckles, also known as Rigging Screws or Bottle Screws, feature a sleek, aerodynamic body design resulting in a rigging tensioner that is stronger than the appropriate diameter wire, including the higher load rating of compacted strand.

Sta-Lok Bronze Turnbuckle Open Bodies are forged from high tensile, bronze alloy with a bright polished chrome finish.

British Manufacturer Sta-Lok are a British manufacturer with excellent foundations for consistently delivering top quality marine fittings:


Sta-Lok launched their wire products into the marine market at the London International Boat Show, Earls Court in 1972.

Sta-Lok introduced their new design of Compression Wire Terminal in 1973 with an innovative DIY concept that simplified the process and made it a practicable alternative to hydraulic swaging for amateur and professional riggers.

Important things to remember about Sta-Lok DIY Compression Wire Terminals.

All terminals are supplied with wedges suitable for 1x19 wire unless otherwise specified.
For 7x19 or 7x7, use prefix 8 instead of 1 e.g. 833 = Sta-Lok eye
For Dyform/Compacted Strand, use prefix D before the 1 e.g. D133 = Sta-Lok eye

The larger diameter thread options on threaded stud terminals are strongly recommended for use with Dyform/Compacted strand wire ropes.

All terminals are suitable for both right-hand lay and left-hand lay wire construction.

All terminals are designed for use with stainless steel wire ropes - using stainless steel terminals with galvanised wire rope will cause galvanic action between the terminal and the wire resulting in rapid failure of the wire.

Sta-Lok Terminals are not suitable for use with wire ropes with fibre cores.
