Test Plates

FILLABLE TEST PLATE ORDER FORM

Test plates are important inspection items. Their proper use will call attention to the problems before the fasteners cause assembly or warranty problems. Untapped test plates are required to properly test tapping screws for their ability to drive and to detect the presence of hydrogen embrittlement. Tapped test plates are required to test machine screws and bolts which are electroplated, and Rockwell C30 or harder, to detect the presence of hydrogen embrittlement. Greenslade Fastener Test Plates meet the following requirements:
      • ASME B18.6.4, B18.6.5M
      • DIN 7500-1, 7513, and 7516
      • FIP-1000.1-7
      • Ford ESS-M1A160-A, ES-20003-S1000, WA-971
      • GM 6010M, 617M, 6171M, 6202M
      • ISO 2702
      • JIS 1055
      • SAE J81, J78, J993, J1237
      • IFI-112, 503
Custom plates are available upon request
