Flex Lock Nuts Dimensions
| TYPES | APPLICATIONS & FEATURES |
MATERIALS | STANDARD SIZES | |
|---|---|---|---|---|
| UNC | UNF | |||
| Full Height Heavy-Duty Steel | One-piece, all-metal locknut. Full size, heavy-duty hex for maximum strength and wrenchability. | Steel Stainless Steel Brass Aluminum | 1/4”-2 1/2 | |
| Full Height Light Hex | Full height, light hex for better wrench clearance and lighter weight. Both, for a broad range of industrial and commercial applications. | Steel Stainless Steel Brass Aluminum | 2 - 1” | 2 - 2 1/2” |
| Thin Height Heavy-Duty Hex | Exceptional strength in low height nut because all threads are load-carrying. Combines ruggedness with space savings. Also available in light hex with 20% less weight and 30% less height for compact or “tight” assemblies. | Steel Stainless Steel Brass Aluminum | 1/4”-1 1/2” | |
| Thin Height Light Hex | Steel stainless Steel Brass Aluminum | #6 - 1” | 6 - 2” | |
| Microsize | For miniature threaded joints in small assemblies. Uses triangular displacement of the threads for positive locking power and optimum strength to weight ratio. Controlled locking torques provide accurate preloading of bolts, stufs, and screws. Ideal for instruments, radar, and electronic equipment. | Steel Stainless Steel Brass Aluminum | #0 - #4 | 0 - |
Scope
The ASTM A194 specification covers carbon, alloy and stainless steel nuts intended for use in high-pressure and/or high-temperature service. Unless otherwise specified, the American National Standard Heavy Hex Series (ANSI B 18.2.2) shall be used. Nuts up to and including 1 inch nominal size shall be UNC Series Class 2B fit. Nuts over 1 inch nominal size shall be either UNC Series Class 2B fit or 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the marketplace and are often substituted for ASTM A563 grade DH nuts due to the limited availability of DH nuts in certain diameters and finishes.
