DRILLED THREADED CUT

Drilling Cutting Threading

Additional operations performed on fasteners are a regular feature in the fastener market place.

There are a limited number of companies that have the facilities or skills to carry out this work.

Drilling requires the accuracy and the ability to drill through high tensile steel, to hold the thread with out damaging it and to remove the bur after drilling.

Cutting both unthreaded, threaded rods and rebar and the ability to thread rebar are both skilful activities performed on long lengths of product.

CNC drilling, and bench drilling are both available services to fastener companies.

Volume runs are generally carried out on CNC machines or gang driller, drilling machines with multiple heads.

Bench drill is for small batches.

Drilling can take place through the across flats, through the screwed body and through the centre of the screw; in any direction the fastener distributor demands.
Cutting

Cutting fasteners to change a standard length to a special length is standard practice for headed fasteners, particularly small quantities. Cutting can be via a CNC machine, lathe or a production saw. The advantage of using a turning method to part off the fastener is that a chamfer can also be added.

Allthread studding is regularly cut to different lengths, a number of specialist fastener companies stock precut lengths.

90 degree cutting is standard practice on studding, 45 degree is also in demand.
Threading and Cutting Rebar

Cutting and threading rebar presents challenges that only a small number of companies have been able to master. The length and irregular surface are difficult to contain while placing threads on the end of lengthy bars.
