Description
Bronze Stemball & Blank represents versatile rigging hardware engineering, combining the proven Sta-Lok Forged Turnbuckle design with threaded stemball articulation and blank termination for maximum installation flexibility. This sophisticated assembly features a precision Threaded Stemball (186) at one end with a blank termination at the other, providing the ideal solution for custom rigging applications requiring multi-directional movement capability combined with bespoke termination requirements.
Available in seven thread sizes from 1/4" to 3/4" UNF with comprehensive dimensional specifications, Bronze Stemball & Blank accommodates diverse rigging requirements where angular flexibility is essential. The stemball dimensions range from 14.6mm to 28mm diameter with adjustment capabilities from 76mm to 168mm, ensuring optimal performance for complex rigging geometries and load vectors.
The advanced Sta-Lok Forged Turnbuckle design exceeds the breaking load of today's high-strength compacted strand wire ropes through superior forging and machining processes utilising high-strength bronze alloy construction. The aerodynamic design philosophy creates one of the strongest and most elegant bronze turnbuckles available on the world market today, optimising strength-to-weight ratios whilst accommodating the complex load vectors associated with articulating connections.
The precision Threaded Stemball termination provides multi-directional articulation essential for applications such as spreader ends, deck cups, coquilles, and complex rigging systems where load direction varies throughout sailing operations. The blank termination allows for custom rigging solutions including eye swages, or mechanical connections to suit specific installation requirements. The high-quality polished chromium finish ensures superior corrosion protection and maintains lustrous appearance throughout extended marine exposure.
