UNF Socket Cap Screws - High Tensile Grade 12.9 - Self Colour
Product Description
A UNF (Unified Fine Thread) Cap Screw in Self Colour (Unplated). The Imperial Cap Head has a deep hexagon socket and an imperial hex driving bit or wrench key is used to tighten the screw.
UNF Cap Heads have a fine thread. They are frequently used in cases where thread engagement is minimised due to thinner wall thickness. Fine series threads have less tendency to loosen under vibration than coarse threads due to their higher load capability.
The length is measured from below the head. Grade 12.9 provide the highest level of strength, clamping and fatigue resistance when tightened to the recommended torque figure. They are ideal for high stress applications or for when a high strength fastener is required.
