- 제7항에 있어서, 나사산이 테이퍼형 진입부로부터 완전한 나사 직경으로 급격히 상승되는 것을 특징으로 하는 나사.
- 제8항에 있어서, 테이퍼형 진입부가 나사산이 없는 원추형점으로 구성되는 것을 특징으로 하는 나사.
- 제9항에 있어서, 나사산이 없는 원추형 점의 정점 각이 30°인 것을 특징으로 하는 나사.
- 전기 어느항에 있어서, 나사산이 형성되지 않은 자루 부분을 나사산이 형성된 부분과 두부 사이에 마련하고, 상기 부분의 직경이 나사산이 형성된 부분의 외경보다 작은 것을 특징으로 하는 나사.
- 제1항 내지 제10항중 어느항에 있어서, 나사산이 형성된 부분이 진입부로부터 두부의 하면까지 연장된 것을 특징으로 하는 나사.
- 전기 어느항에 있어서, 나사산이 없는 상승된 거치부를 두부 직하부에 마련하고, 상기 부분의 직경이 나사산이 형성된 부분의 외경과 동일한 것을 특징으로 하는 나사.
- 도면을 참조로 하여 설명한 바와 같이 제작 및 배치된 나사.
- ※ 참고사항:최초출원 내용에 의하여 공개하는 것임.
