ASTM F467 Nuts

ASTM F467M specification also known as metric specification for ASTM F467 which covers the requirements for commercial wrought nonferrous nuts in nominal thread diameters M6 to M36, whereas ASTM F467 nut specification covers the imperial (inch) standard requirements for commercial wrought nonferrous nuts in nominal thread diameters ¼” to 4” inclusive in a number of alloys in common use and intended for general service applications. In general these nuts are used with bolts, cap screws, Studs and Threaded Rod as per ASTM F468 / F468M Specification.

ASTM F467 / F467M Nuts, Hex Nuts, Metric, Inch Supplier & Manufacturer

Based on the applications, temperature range and test methods ASTM F467 is further divided into various groups viz.
Nickel & Nickel Based Alloys Like Inconel, Monel & Hastelloy – Tested in accordance with ASTM E38, E76 and E354.
Non Ferrous Alloys Like Brass, Phosphor Bronze, Silicon Bronze, Manganese Bronze and Copper-Nickel – Tested in accordance with ASTM E53, E54, E62, E75and E478
Aluminum Based Alloys – Tested in accordance with ASTM E34, E101 and E227 Titanium Based Alloys – Tested in accordance with ASTM E 120 and E1409

Unless otherwise specified ASTM F467M Hex nuts and heavy Hex Nuts shall be manufactured in accordance with dimension requirements of ASME B18.2.4.1M. The Nuts shall comply thread tolerance as per ASME B1.13M Class 6H.
Imperial size nuts as per ASTM F467 specification shall comply to dimensional standard ASME B18.2.2 for both hex and heavy hex nuts. Thread tolerance shall be in accordance with ASME B 1.1 Class 2B.
