SWG 19900403519 Wood screw 4 mm 35 mm Star socket Steel zinc plated 1000 pc(s)

Wooden screws TX countersunk head, pitch thread, galvanized

TX drive:
Good power transmission through six force attack surfaces (line contact), no drive-out effect (cam-out effect is omitted through cylindrical form), thus long life-span of bit, machine processing is possible, good torque transmission

Countersunk head with cut ribs:
Surface-flush lowering of the screw head leads to a perfect processing optics, lower energy and application force through easy and clean lowering of the screw head, useful length corresponds to the complete screw length

Lower head reinforcement:
User-safety through highest resistance against tearing

Partial thread:
Optimum processing result by a tight sealing of the upper layer of wood

Shaft cutter (friction part):
Less friction on the screw shaft ensures tool-protecting workmanship, less energy and effort because the shank cutter acts like a drill, reduction of the insertion resistance, easy processing of long screws

Coarse thread:
Always brings the optimum processing speed for each screw length, faster screwing through thread geometry leads to time savings during processing

Cutting notch:
Less cutting forces due to drilling effect, reduced clearance angle of the wood makes possible cross-section screwing; machining of the wood fibers
