Detailed Specifications
FEATURES:
1. The pressure displacement principle provides a fastener made of a relatively strong material installed into a relatively soft mounting material.
2. The BA fastener provides a steel threaded hole in a relatively soft material, flush with both surfaces of the mounting sheet, except for the protruding self-locking appendage.
NOTES:
1. High carbon steel (Material Code D) parts are stock items. Parts made of type 303 corrosion resistant steel (MIL-S-7720) are available, on order, by using Material Code C.
2. Parts are installed by pressure displacement principle as illustrated by figures. Pressure is applied between a punch and an anvil which may be installed in any suitable equipment, such as hydraulic or impact punch presses. A clearance hole is shown in the punch to accommodate the self-locking appendage. Pressure to be applied will vary with fastener size, sheet thickness and type of material used.
3. Sheet material must be ductile and capable of forming into knurled recess of fastener without stress cracking.
4. In all cases the fastener should be installed to allow screw threads to enter the side opposite the large flange. When the screw is cinched at installation, the forces are applied against the large flange.
SPECIFICATIONS:
1. Steel fasteners (Material Code D) are made of chrome molybdenum alloy per AISI4140 (or equal).
2. Steel fasteners (Material Code D) are cadmium plated per QQ-P-416, Type II, Class 2.
3. Corrosion resistant steel fasteners (Material Code C) are passivated per SAE-AMS-2700.
