Preventing drywall rust discoloration

Drywall screws can be exposed to high humidity atmosphere, during long sea transport or storage and processing, which often leads to early rust discoloration.

This can cause financial damage, as the screws may no longer be used in a professional way or previously performed work may need rectification. The costs of drywall screws may be only a small percentage of the total construction investment, but they can lead to big losses if rust problems occur and complete walls or ceilings have to be repaired. BLUEfast500® drywall screws users can avoid such problems. The BLUEfast500® drywall screws provide all the known advantages of ‘normal’ drywall screws, but with the advantage of 10x higher rust resistance.


Despite its higher resistance to rust, the chrome 6 free BLUEfast500® coating is much more environmentally friendly than a conventional phosphate coating. From stock adunoX GmbH offers a complete range of drywall screws with BLUEfast500 coating, including fine, coarse and drill point and a cementitious board screw in bulk and collated.

& SAVE! Guaranteed, visually checked, tension

Tension Control Bolts are replacing conventional high strength friction grip and pre- loaded bolts throughout the steel construction industry simply because they are quick and easy to install. Guaranteed tension together

with visual inspection removes the likelihood of operator error and assures engineers that connections

are tightened in accordance with European specifications. TCBs are used extensively by the

UK rail industry for new bridges, re-strengthening of existing bridges and rivet replacement. The UK highways agency also specifies TCBs for their bridges and gantries. Tension Control Bolts Ltd has its

own metal coating plant producing an environmentally friendly

process called Greenkote® which is comparable to galvanising, although it is harder wearing and readily accepts all paint systems without the need for acid etching. As the largest manufacturer, designer and distributors of TCB’s in Europe, TCB are able to offer ex-stock delivery of both its range of bolts and shear wrench tools as well as providing full technical support and installation training.
