This reference includes 50 kits composed by
1 x Nail Screw NP 4,0x57, zinc plated
1 x Drop-in plug SD-I 6 X 50 SB
The nail plug NPC 6-50 is your first choice for the quick fixing of frames, slats, channels, foils, electric clamps and many more. The accurate tuning between plug and zinc plated nail screw results in optimal expansion and secure fastening is guaranteed by high pull out loads. Additionally the nail plug NP contains a specialised integral barrier to avoid premature expansion, while the nail screw head is protected by a raised ring during hammering in. This way the PZ2 drive remains intact and enables you to screw out and remove your application. You save time as all diameters are pre-assembled.

The countersunk plug allows smooth mounting in the fixture.
