New range of bolts and nuts available from Exafast

Supplier News

Due to demand, Exafast has added an extensive range of 8.8 Metric bolts, nuts and setscrews with fine and extra fine thread pitches to its range of quality fasteners. This new range is known as the Metric Fine range

Fasteners with fine and extra fine thread pitches can exhibit the following advantages when compared to the course thread pitch equivalents:

  • Greater tensile strength for the same nominal diameter and strength grade/property class
  • Greater resistance to self-loosening under vibration
  • Better suited to fine adjustment.

High tensile strength and an extensive range of diameter and thread pitch combinations make Exafasts’ Metric Fine range suitable for a wide variety of applications including automotive, agricultural machinery and general industrial use.

The Metric Fine range includes sizes from M8 to M24, with bolt and setscrew lengths from 20mm up to 150mm.

For further convenience and flexibility, the complete range is stocked in both black and bright zinc electroplated finishes.

The Exafast Metric Fine range is manufactured to comply with the dimensional and mechanical strength requirements of DIN 931 (bolts), DIN 933 (setscrews) and DIN 985 (nuts).

As with every product in the Exafast high tensile range, every batch of Metric Fine bolts, nuts or setscrews is rigorously tested in Exafasts’ own fully equipped Fastener Testing Laboratory.

Batch testing certification is available upon request.
