Quality Fastener Facts

KEEP-FILL® has partnerships with North America's top producers of fasteners and threaded components. Use of domestic products ensures trace-ability, quality, and reliability.

Use of quality-manufactured products is perhaps the first step in ensuring maximum fastener performance. Equally as important, however, is the proper use of fasteners for each given application. 

QUESTIONS TO CONSIDER: Are your skilled trades' people using heat-treated nuts and washers with heat-treated bolts? Are they using 8.8,10.9 or 12.9 metric socket head cap screws? Are grade 2 products being used in safety critical applications? Are 18-8 stainless steel bolts being used in corrosive applications that would be more appropiately suited to 316 stainless steel?

Those are the questions we will continuously ask beginning with your plant survey and as our Inventory Management Specialists visit your location daily, weekly or monthly, taking the following into consideration:

  • Vibration 

  • Load Conditions 
  • Temperature 
  • Joining Materials 
  • Corrosion 
  • Installation

Our field support team analyzes your bolting requirements based on those types of concerns and technical recommendations are presented to plant management and personnel. This becomes the basis of standardization for the types of fasteners stocked, maintained, and used. Proper selection and availability of fasteners enhances reliability, performance and most importantly, safety .

Services include:

  • Bolted Joint Analysis 

  • Torque Seminars 

  • Product Training 

  • Fastener Testing 

  • Failure Analysis 

  • Torque Audit Services 

  • Fastener Blueprint Documentation

Please call for details or contact us for more information.

  • Most heat-treated fasteners are available domestically.

    Domestic Standards such as ANSI and SAE have tighter quality requirements than some foreign standards (such as DIN or JIS). 

    Domestic fastener producers offer improved deliveries. 

    Domestic fastener manufacturers produce products competitively.


A poor quality bolt costing only pennies can cost millions when equipment fails, production stops, or injuries occur. KEEP-FILL® offers the most comprehensive selection of domestically produced standard fasteners in the country.
