BS EN 4845:2022标准规定了一种用于航空航天应用的螺钉,其具有100°埋头、螺旋驱动凹槽和短螺纹。该螺钉适用于耐热钢FE-PA2601 (A286),并经过钝化处理。该标准对螺钉的分类为900 MPa (常温)/650 °C。

该标准的适用范围包括航空航天领域的各种应用,例如发动机、涡轮机、燃气轮机、航空电子设备等。该标准的要求适用于所有生产和供应该类型螺钉的制造商和供应商。

该标准要求螺钉的材料必须符合耐热钢FE-PA2601 (A286)的要求,并经过钝化处理。螺钉的表面应平整、光滑,无明显的裂纹、划痕和氧化。螺钉的头部应具有100°的埋头角度,并且应具有螺旋驱动凹槽,以便于使用螺丝刀进行拧紧。螺钉的螺纹长度应为短螺纹,以确保螺钉的强度和稳定性。

该标准还规定了螺钉的分类,即900 MPa (常温)/650 °C。这意味着螺钉在常温下的最小拉伸强度为900 MPa,在650 °C下的最小拉伸强度也为900 MPa。这种分类可以确保螺钉在高温环境下的稳定性和可靠性。

总之,BS EN 4845:2022标准规定了一种用于航空航天应用的螺钉,其具有100°埋头、螺旋驱动凹槽和短螺纹。该螺钉适用于耐热钢FE-PA2601 (A286),并经过钝化处理。该标准对螺钉的分类为900 MPa (常温)/650 °C,以确保螺钉在高温环境下的稳定性和可靠性。
