Martin Audio HTKCT05 – M8 Forged Eye Bolt for Loudspeaker Rigging

Product Overview

The Martin Audio HTKCT05 is a forged steel M8 shouldered eye bolt designed for the suspension and rigging of Martin Audio loudspeakers fitted with M8 eye bolt mounting points. The shouldered design distributes load forces into the enclosure cabinet structure rather than concentrating stress at the thread, improving load-bearing reliability in permanent suspension applications. With a working load limit of 450 kg (992 lbs) per bolt, the HTKCT05 meets the structural demands of professional loudspeaker flying and rigging installations.

Product Description

The HTKCT05 threads directly into the M8 rigging inserts integrated into compatible Martin Audio loudspeaker enclosures, including XE Series stage monitors, CDD Series loudspeakers, and other Martin Audio products specifying M8 eye bolt rigging hardware. The shouldered construction provides a positive seating surface against the enclosure cabinet, ensuring the bolt does not pull through under load. Forged steel construction provides superior grain structure and impact resistance compared to cast or machined alternatives, which is a standard requirement for overhead rigging hardware used in occupied venues.

Each HTKCT05 is sold individually. For multi-point rigging configurations typical of flown line array or subwoofer applications, multiple eye bolts are required per enclosure per the rigging specifications provided in the Martin Audio product documentation. Always refer to the Martin Audio rigging guide and local structural safety regulations when designing suspension systems for occupied spaces.

Key Features

• Forged Steel Construction — Superior grain structure and impact resistance compared to cast or machined alternatives, meeting professional rigging hardware standards.
• Shouldered Design — Load distribution into the enclosure cabinet surface reduces thread stress concentration and improves suspension reliability.
• M8 x 1.25 Thread — Direct fit into M8 rigging inserts on compatible Martin Audio loudspeaker enclosures.
• 450 kg Working Load Limit — 992 lbs per bolt working load supports professional loudspeaker suspension requirements in permanent and touring installations.
• Compact Shank — 31.7mm shank length provides secure thread engagement with M8 inserts without over-penetrating enclosure walls.
• Lightweight — 0.08 kg per bolt minimises additional mass in weight-sensitive suspension configurations.
