Ultra Low Hex Socket Cap Screws are suitable for use in narrow spaces where raised head screws would not usually fit.
When fastened, they sit flush against the surface giving an aesthetic low profile finish to the application. These screws are used in a range of applications and industries including robotics and electronics.
The socket drive of these screws allows them to be used in locations where externally driven fasteners are not desirable.
Ultra Low Hex Socket Cap Screws are manufactured from Stainless Steel, Grade 10.9 Steel Self Colour, Grade 10.9 Steel Black / Nickel Plated, and Grade 10.9 Steel Zinc.
Available at Fastenright in thread sizes M2 to M10 as standard, with lengths up to 30mm. Optional thread locking patches can also be supplied.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
