Osculati DIN 963 Stainless Steel Slotted Countersunk Screw Sets with Nuts and Washers

Osculati stainless steel fastening sets combine slotted countersunk head machine screws according to DIN 963 with corresponding DIN 934 hexagonal nuts and DIN 125 flat washers. These assortments provide the principal components needed for compatible threaded fastening connections.

The DIN 963 machine screws feature flat countersunk heads with a straight-slot drive. The tapered head underside fits into a suitably prepared countersunk recess, allowing the screw head to sit flush with the mounting surface. A compatible flat-blade screwdriver is used for installation and removal.

The accompanying DIN 934 hexagonal nuts provide threaded fastening, while the DIN 125 flat washers help distribute the clamping force over the contact surface. The screws have metric threads and are intended for use with matching nuts or threaded holes.

The stainless steel construction provides corrosion resistance for suitable marine, outdoor and general mechanical applications. The range includes eight dimensional variants with nominal metric thread sizes M3, M4, M5, M6 and M8 and screw lengths from 20 to 60 mm.

Each variant is supplied in a blister pack with a specified screw quantity. Matching nuts and washers are included, although their individual quantities are not separately stated in the supplied catalogue information.
