Osculati A2 AISI 304 Stainless Steel Phillips Countersunk Wood and Chipboard Screws DIN 7505A
Osculati DIN 7505A wood and chipboard screws are manufactured from A2 (AISI 304) stainless steel and designed for fastening compatible chipboard panels, wood and plastic components. They feature a flat countersunk head, a cross-recessed drive and a pointed threaded shaft.
The flat countersunk head has a tapered underside that allows it to sit flush with the mounting surface when installed in a suitable countersunk recess. The cross-recessed drive enables tightening and removal using a matching Phillips screwdriver or driver bit.
The pointed tip and coarse thread are designed to engage suitable wood-based and plastic materials. Depending on the substrate, material thickness and proximity to an edge, a pilot hole may be required to reduce splitting or damage during installation.
Unlike metric machine screws, these wood and chipboard screws are intended to engage directly with the fastening material rather than with a standard metric nut or tapped hole.
A2 (AISI 304) stainless steel offers corrosion resistance for general indoor, outdoor and appropriate marine applications. For installations exposed to prolonged saltwater contact or high chloride concentrations, the suitability of this material should be assessed.
The range includes 36 dimensional configurations across six nominal screw diameters: 3, 3.5, 4, 4.5, 5 and 6 mm. Available lengths range from 15 to 80 mm, depending on the selected diameter. Each version has an individual Osculati part number and is supplied in a cardboard box containing a specified number of screws.
