Polycarbonate
Countersunk Screws
All our Polycarbonate (PC) countersunk (also known as Flat Head) screws featured comply with DIN 965 specification and are transparent in colour.
HPP’s Countersunk screws are manufactured with a standard Phillips cross head drive type (ranging from drive #1 to #3), this allows for more than adequate torque for the fastener specification.
The standard head angle for all our countersunk screws is 90 Degrees.
Our PC screws are commonly used in general applications due to low unit costs, high impact strength and non-corrosive properties.
Certificate of conformity available on request.
