Why us? Proven ability to develop new designs

Throughout the years, we have helped Powers Fasteners innovate knurled stainless wedge anchor bolts and tapped into the foreign markets and stainless bolt industries.  Currently we machine stainless anchor bolts for Sanko Techno Co., Ltd.

In 2015, we set up a sourcing department to help our customers develop Custom Fasteners like special large bolts, long stainless bolts, stainless nuts, long stainless screws, cold forge bushing, timber fastener, and stainless stamping parts.

    The fasteners have been received and look very good thank you.

    We have just received the stainless nuts from DHL and we are very impressed with the quality. 
    Thank you for making this a great transaction and I will contact you when we require more stainless steel fasteners.  Best regards, Steve

  • Post-Sales Follow-Up (July 30, 2021) Stainless Washers for Valves

    Yes, everything is fine.  Thank you for asking.  I hope everything is well with you also.   The washers are working good,  It will take me some time to go through that many because orders have been slow for the valves that they are used with.  I am only using about 100 per month right now. Best Regards, Jim
