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.
Anu-Lok Cap Head Seal Screws have a cap head design for better torque control and feature a built-in sealing mechanism that is designed for holding a gas-tight seal. Made of stainless steel, which has high corrosion resistance and is somewhat magnetic.
These screws utilize Anu-Lok 180 (AnuLok), a reusable nylon patch that works like a nylon nut. During installation, the nylon patch contracts to fill the gap within the threads, creating a holding mechanism that prevents the screw from detaching due to vibrations or mechanical stress.
With a hexagonal socket head, they can be easily tightened or loosened using an hexagonal wrench or key.
The Anu-Lok Cap Head Shoulder Screws feature a cylindrical shoulder that distinguishes the screws head from its threaded section. This shoulder is precisely machined to serve as a bearing surface for the screw head.

This range of Seal Screws features a button head with a hexagonal drive. Hexagonal drives are ideal for precision assembly and are used where less surface area is available. They are made from Stainless Steel that provides good resistance to corrosion and is slightly magnetic..
Seal screws are a type of fastener designed with an o-ring to provide secure bi-directional protection against contaminates such as gases and fluids in various applications, minimising the risk of damage to sensitive equipment. They prevent the entry of water, dust, or other contaminants, ensuring a secure, reliable connection.
Seal screws are used in threaded and non-threaded holes in applications such as cabinets or used in the automotive and electric industries. Please note: Our seal screws are designed for use in applications where sealing properties are required. It could be confused with standard fasteners, these do not require sealing properties and with an O-ring you will not get a sealing property like you get with seal screws and may damage the ring.
This range of sealing screws has a cap head with a torx socket drive, incorporating an O-ring that is compressed-squeezed between the head, the socket drive and the mating surface to complete the seal. Manufactured from stainless steel, which provides good corrosion resistance and is slightly magnetic.

It could be confused with standard fasteners, these do not require sealing properties and with an O-ring you will not get a sealing property like you get with seal screws and may damage the ring. Clearance holes are recommended for optimal sealing performance (see measurements below). Clearance hole depth is 2-3 times the thread pitch; threads are metric coarse pitch.
This range of Cap Screws are available in a choice of hexagonal drive or Torx drive. Hexagonal drives are ideal for precision assembly and are ideally used where less surface area is available. Torx drives provide a positive-engaging, fast-locating technique for transmitting drive torque with less necessary downward pressure. Available in a choice of two low head options: ultra low head and extra low head.
The Ultra Low Head options helps reduce the screws overall head height space, which means no countersinking is required, unlike flat head screws.
The Extra Low Head option has an extremely low profile and does not need a countersunk location hole. The lack of necessity for the countersink allows for thinner materials to be used, saving weight. These screws are suitable for machine and equipment applications, with minimal clearance.
The captive screw retainer flange is an alternative to either tapping the panel or using a retainer washer. The retainer flange is fixed to the panel by swaging the head into a countersunk hole.
The captive screw is then simply threaded through the flange and is retained in the panel.
The flanges are made from either Stainless Steel which has good corrosion reistance or Aluminium, which has good thermal conductivity.
Captive Screws are fasteners designed to remain attached to the component they are securing, even when fully loosened, providing convenience, security and ease of use in a variety of applications. They are a popular choice for applications where screws need to be removed frequently or where safety is a concern, as these screws will stay firmly in place and will not loosen from the assembly.
