ForgeFix Multi-Purpose Single Thread Countersunk Screws (Zinc Yellow Passivated) - 4.0 x 40mm (1200 Pack Tub) (MPS440YT)
Tub of yellow passivated 4.0 x 40mm countersunk multi-purpose screws ideal for everyday use in a variety of joinery, electrical and plumbing applications.
The single thread of these screws leads to both quicker insertion and higher pull out values in low density materials such as timber since the structural integrity of the material is maintained within the wider pockets of the thread resulting in a greater holding power.Treated with a zinc yellow passivated finish to improve the corrosion resistance of the screws and give an appealing yellow colour.Suitable for a wide range of applications in timber, PVCu, chipboard and other similar materials.The countersunk head of these screws means that they will sit flush with the materials surface resulting in a smooth finish.A pozidriv head means that these screws can be driven in faster with a reduced chance of a cam out since the pozi cross-head grips better than other head shapes.The thread of these screws is wax coated to increase both the ease and speed of insertion.
