Metric Ultra Low Head Socket Shoulder Screws are manufactured according to ISO 7379, and are designed with a large unthreaded shoulder below the head, which is machined to a very high tolerance of +/-0.025mm. The unthreaded portion of these components is intended to be used in applications requiring highly precise sliding or rotation. Ultra Low Head Socket Shoulder Screws are also fitted with a reduced head for space conservation.

Ultra Low Head Socket Shoulder Screws are ideal for use with Accu's Hexagon Socket Drive Bits and Hexagon Socket Key Wrench ranges.

Ultra Low Head Socket Should Screw Materials

Ultra Low Head Socket Shoulder Screws can be manufactured from both A2 and A4 (Marine Grade) Stainless Steel.

Ensure your Ultra Low Head Socket Shoulder Screws stay secure with our advanced pre-applied thread-locking patches. Whether you need AccuLock Threadlocker for essential fastening, Anu-Lok 180 for added grip, or Precote 80 for maximum performance, we have the right solution. For a refined aesthetic, AccuBlack chemical blackening reduces glare while enhancing the surface finish.
