Vented Countersunk Machine Screws

Vented screws are fasteners with a hole drilled through the middle that allow gases trapped at the bottom of a blind threaded hole to escape through the core and provide airflow within an application. The screws are a common option for HV and UHV systems because their centre vent feature reduces virtual leakage from high vacuum systems.

This range of Vented Screws features a countersunk machine head with a hexagonal drive. Hexagonal drives are suitable for precision assembling and when there is limited surface area. They are made from Stainless Steel.

  • Their centre vent feature reduces virtual leakage from high vacuum systems.
  • Ideally suited for usage in sealed enclosures, housings, and machinery.
  • Hexagonal drives are suitable for precision assembling.

Joint Connector Bolts

Joint Connector Bolts, which are often known as Furniture Connector Bolts or more simply Joint Bolts, can be used with Joint Connector Nuts & Barrel Nuts. Our customers regularly purchase our Cross Dowel Barrel Nuts too.

Made from zinc plated steel, for superior oxidation, they are ideal in the assembly of flat-packed furniture. Quick and easy, thanks to the flat head with a hexagonal drive. They can be fitted using an M4 Allen Key (not supplied).

  • Compatible threads; M6 Joint Connector Bolts and M8 Joint Connector Bolts.

Shoulder Bolts - Hex Head

These Shoulder bolts, also known as shoulder screws, are a type of fastener with a plain section shoulder in between the head and threaded portion of the screw. The shoulder part is machined to a precise tolerance for locating, fastening, or rotating parts.

It decreases stress concentration and lowers the likelihood of damage or failure. It is also durable, corrosion-resistant, and nonmagnetic. It can handle high loads, vibrations, and harsh environments.

Its hexagonal-shaped head offers a comfortable and stable grip for tightening and loosening the bolt. The hex head shape enables simple torque application with a wrench or socket, delivering a tight and solid connection. It is widely utilised in various sectors, including automotive, industrial, electronics, and construction.

  • This shoulder part is machined to a precise tolerance for locating, fastening, or rotating parts.
  • Its hexagonal-shaped head offers a comfortable and stable grip for tightening and loosening the bolt.
  • It is durable, corrosion-resistant, and nonmagnetic.
  • It can handle high loads, vibrations, and harsh environments.

Thrust Screws - Brass Pad

These brass pad thrust screws are designed to provide a controlled bearing surface for components that must be precisely positioned and attached while minimising axial movement or damage to the mating surface. It guarantees smooth, controlled action while reducing friction and wear.

As the screw turns, the brass pad applies pressure on the surface it touches, allowing for controlled movement or adjustment. It provides a secure and stable point of contact and is extremely wear-resistant.

It is simple to install under pressure, softly clamp or push threaded spindles, shafts, or surface-treated parts, and place more delicate parts. It is frequently utilised in mechanical assembly, precise instrumentation, calibration, and alignment.

  • Offers a controlled bearing surface for components that must be precisely positioned and attached.
