Anu-Lok Cap Head Captive Screws

In production

Anu-Lok Cap Head Captive Screws are intended to offer a secure and vibration-resistant attachment, while remaining permanently connected. Features a cap head design that enables simple torque application with tools like hexagonal keys. Anu-Lok 180 (AnuLok) is a reusable nylon patch that works like to a nylon nut. During installation, the nylon patch contracts to fill the gap within the threads.

The specialised retention mechanism prevents complete detachment from the assembly, due to vibration or mechanical stress, while allowing for repeated fastening and unfastening. This feature is useful in applications requiring maintenance or regular access. Applications include electronic enclosures, machinery guards and structural components.

Please note: These screws have a reduced diameter shank and should not be tightened to the recommended torque for an equivalent machine screw of size d1.

  • The screws captive nature complies with the Machinery Directive 2006/42/EC (equivalent to ISO 4762) that guarantees compliance with safety and regulatory standards, especially in industries where loose hardware may represent a risk.
Material: 303 Stainless with thread lock Series Code: SRP0154
