개요


본 제품은 알루미늄, 동, 주물등의 경금속이나 플라스틱과 같은 강도가 약한 재질의 모재에 대한 암나사 보강용으로 개발된 제품이며 인장강도와 내마모성이 우수하여 높은 하중을 잘 견딥니다.

재질 :
Steel (Unhardened steel , Case-hardened steel)  
Stainless steel(1.4105 and 1.4305)  
Brass

사용방법
1. 권장하는 수치로 드릴 작업을 하세요.
(필요에 따라 Countersink 가능)
2. CUTTING SLOT 부분이 아래로 향하게 한 상태로
전용툴에 돌려 끼우세요.
3. 전용툴과 제품이 삽입하려는 곳에 수직으로
향하게 한 후 제품을 삽입하세요.
4. 제품의 깊이는 가능하면 모재의 표면으로 부터
0.1~0.2mm 아래로 하여 주세요.
5. 역회전하여 전용툴을 빼주시면 작업이 종료 됩니다.

The Insert in the workpiece…(Reference)
Installation recommendation
Avoid any tilting between the Insert and the screw under the head or in the thread. For this reason, in the case of
adjusting screws the INSERT is driven in to a depth of >= 1mm. Studs are countersunk to the floor surface of the
blind hole (see illustration).
Recommended borehole diameter for easy assembly
Other diameters may require lubrication
Retaining hole
The retaining hole can be simply drilled or already provided for in the casting.
It is generally not necessary to countersink the hole. However, we do recommend that
you take care not to warp the workpiece surface when screwing in the Insert.
Material thickness:
Length of the Insert = smallest Admissible material thickness M.
Depth of the blind hole:
Minimum depth-T see Works Standard.
Borehole diameter:
Brittle, tough and hard materials call for a larger borehole than soft or elastic materials.
For guideline values, see the table above.
Edge distance:
The smallest still admissible edge distance depends on the planed stress level and the elasticity of the material
into which the Insert is screwed.
Guideline values for light alloys:
W ≥ 0.2 to ≥0.6 E
Guideline values for cast iron:
W ≥ 0.3 to ≥0.5 E
E = Outside diameter of the Insert [mm]

The adjacent table is used to determine the recommended bore hole diameter depending on the material of the workpiece and the Insert type / dimension.

Example:
Light alloy workpiece (Rm=280 N/mm2), Internal thread M8,
recommended bore hole diameter for
PP-201: 11.2 to 11.4 mm
PP-204/205:11.2 to 11.5mm

In case of processing problems (e.g. markedly increased screw-in torque levels ) there is generally no harm in selecting diameter
data in the next highest column. In case of doubt,
we advise carrying out a test.
