⚡ At a Glance
- • Fixing Strength: Full thread and #2-56 sizing ensure consistent engagement in machine-threaded holes.
- • Best for: Precision assemblies and small repairs where a flush countersunk finish is required.
- • Not ideal for: Heavy structural loads or applications that need coarser fasteners.
Flat countersunk head with a hex socket and full thread for compact machine-thread use. Right-hand #2-56 x 3/8 inch sizing, stainless-steel construction, supplied as a 100-piece pack.
Flush Finish – Thanks to the countersunk flat head
Countersunk flat heads sit into a matching countersink so the screw head aligns with or below the material surface. Hex socket drive keeps the head profile compact for a neat finish.
A flush head reduces snagging and gives a tidy appearance, ideal for visible assemblies and trim work.
Secure Engagement – With full thread and #2-56 sizing
Full threading runs the full shank length, engaging mating threads continuously rather than only near the tip. The #2-56 designation identifies thread diameter and pitch for standard machine-thread fittings.
Consistent thread engagement improves pull-out resistance in small machine-thread applications and simplifies alignment during assembly.
Corrosion Resistance – With stainless-steel construction
Stainless-steel material resists oxidation and surface corrosion when exposed to moisture or humid conditions. Right-hand thread is standard for common fastening use.
Stainless-steel fastenings maintain appearance and function over time, reducing the need for frequent replacements in damp environments.
