Lobular Screw

HIGH PERFORMANCE FIXATION WITHOUT USING NUTS

Carbon steel screw, thread rolling machine that needs the pre-drilling in order to be applied in low carbon steel metallic components. Available in flat head and hexagon head.

Request a budget

Benefits

Fixes and locks in a single operation due to the tri-lobular thread

Better productivity, eliminating the need of nuts and lock washer

It laminates the thread by shaping it, while providing greater resistance when subjected to vibration

For systems with vibration, it eliminates the use of locking devices

Considerable reduction in assembling time

Applications

Fixation of metallic sheets and compounds for automotive industry

Fixation of compounds with high vibration ratio in buses, trailers and trucks

Fixation in tubular profiles

Fixation of machines and equipment

1 – ASTM B117, ABNT NBR 8094 and DIN 50021 Standards (red corrosion)
2 – DIN 50018 Standard (admitting 15% red corrosion on screw head)
3 – The test does not apply to the sample. Duration is less than 1 cycle.

Step 1) With a drilling machine, pre-drill the hole using the recommended drill bit, according to tables 2 and 3 of the Technical Bulletin.

Step 2) Fit the recommended socket (hexagon head) or torx wrench (flat head) into the screwdriver and attach the screw.

Step 3) Fit the screw tip inside the pre-drill, and with the screwdriver, tighten the screw until it is fully fixed.
