Specification

Mechanical and functional properties in accordance with DIN 7500-1 (shape PE), case-hardened (-O-) zinc-plated steel, blue passivated (A2K) with slide coating, head dimensions according to ISO 14583

Self-tapping screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, self-tapping does not interrupt the material structure in the receiving thread. Instead, the material is displaced and strain-hardened.

Benefits:

Cost savings

Eliminates thread cutting

Non-cutting thread formation

Low rolling torques with greater thread flank overlap

TRILOBULAR shape of the core diameter combined with the radius profile of the thread flanks

High clamping force

Due to low rolling torques

High load-bearing capacity

Due to large thread flank overlap

Due to strain-hardened counter thread (nut thread)

Protection against loss (reduced likelihood of screw working loose)

Play-free and self-locking thread seating

The formed thread corresponds to a standard metric thread

Where necessary, the GEFU screw can be replaced with a metric screw.

Notice

The suitability of the GEFU
^® for the application or component in question must be determined by testing in advance. Guideline values for suitable hole diameters are specified in DIN 7500-2.

Application

Application area

Examples of materials suitable for this type of non-cutting direct screwing are ductile materials such as steel (up to approx. 500 N/mm²), die-cast zinc, aluminium, copper, copper alloys etc.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
