Bottlescrew

Stainless steel bottlescrews with a jaw-to-swage configuration are designed to tension wire rope in balustrade systems, rigging assemblies, and general stainless cable installations. The combination of a jaw fitting at one end and a swage terminal at the other provides both flexibility in connection and a secure, permanent attachment to the wire rope, making this style of bottlescrew a popular choice in architectural and marine applications.

The jaw end features a clevis and removable pin, allowing easy connection to lugs, eye plates, brackets, or other compatible fittings. This makes installation and adjustment straightforward, particularly in balustrade systems where alignment and precise tensioning are critical. The swage end is intended to be permanently swaged onto the wire rope using appropriate hydraulic or mechanical swaging equipment, ensuring a strong, clean termination that resists loosening over time.

Manufactured from Grade 316 stainless steel, these bottlescrews offer excellent corrosion resistance in demanding environments. Grade 316 includes molybdenum, which significantly improves resistance to chlorides, salt spray, and moisture. This makes jaw-to-swage bottlescrews well suited for outdoor installations, coastal locations, marine environments, and areas exposed to regular wash-down or weathering.

Bottlescrews allow fine adjustment of wire rope tension through the threaded body, enabling installers to achieve consistent tension across multiple cable runs. This is especially important in balustrades and barrier systems, where uniform appearance and compliance with design requirements are essential. Once tensioned, the bottlescrew can be locked in place to maintain stability over time.

Available in a range of sizes to suit different wire rope diameters, these fittings should always be matched correctly to the cable size and load requirements of the system. Using compatible stainless steel components throughout also helps minimise galvanic corrosion and ensures a consistent finish.

For reliable tensioning, long service life, and a clean professional appearance, Grade 316 stainless steel jaw-to-swage bottlescrews are a proven solution for balustrade, rigging, and marine wire systems. Select the bottlescrew size to match your wire rope diameter and application requirements.
