Pennenginering的Pemsert自我限制的冲洗螺母理想地是适合的附件，其中薄金属板需要承载的螺纹比敲击的孔更强，但必须保持平坦，而不会在纸张的任何一侧都没有任何突起。它们可以在弯曲弯曲和成型之前安装，以提供截面中的交配硬件的线程，否则在形成底盘后安装不可访问。他们独特设计的六边形头和弯头技术可确保使用高轴向和扭转强度。最终，螺母将永久安装，永远不会松动或掉落，并保持表面未隔离，以增强组装的功能和化妆品。
The product line includes PEMSERT F™ 300 Series stainless steel types for installation into steel or aluminum sheets and PEMSERT F4™ heat-treated 400 Series stainless steel versions specifically designed for installation into 300 Series stainless steel sheets. Both types are available in thread sizes #2-56 through ¼-20 and M2 through M6. Sheets can be as thin as .060”/1.53mm. For aerospace applications, F nuts can be ordered to conform with US NASM45938/4 aerospace standards.
通过使用足够的力将其六角形头与纸板嵌入圆孔，可以轻松完成安装。然后，头部流动的金属在紧固件的背面小腿周围均匀地流动，以将螺母永久锁定到位。六角形的头部和紧固件的自链设计都结合在一起，可提供高拉动和扭矩的电阻。仅需要配合螺钉才能完成最终组件附件。
Detailed technical literature (PEM® Bulletin F), individual fastener drawings, and CAD models for these RoHS-compliant fasteners can be downloaded at the PennEngineering website.
