S-93405A194 8-32 x 1/2" ASME B18.13 Steel Pan Head Phillips Screws with Split Lock Washer

Key Features & Benefits at a Glance

• Vibration-resistant locking with integrated split lock washer prevents loosening in high-stress environments
• Enhanced corrosion protection through zinc-plated steel construction for extended service life
• Superior driving efficiency with Phillips No. 2 drive design for secure installation and removal
• Maximum thread engagement through fully threaded UNC coarse spacing for stronger holding power
• Precision thread fit with Class 2A tolerance ensuring reliable mating with standard nuts
• High mechanical strength with 60,000 psi tensile strength and Rockwell B70 hardness
• Broad compatibility with rounded pan head profile fitting standard tooling and applications

Professional Applications & Engineering Value

These zinc-plated steel screws with integrated split lock washers provide critical vibration resistance in industrial assemblies where dynamic loads and thermal cycling cause conventional fasteners to fail. The fully threaded UNC coarse spacing ensures maximum thread contact in softer materials and faster installation, while the Phillips pan head design offers flush mounting with superior torque transmission. Engineered for machinery, electrical enclosures, and automotive components, these 8-32 screws deliver reliable clamping force maintenance even under continuous operational stress, eliminating the need for secondary locking mechanisms and reducing maintenance intervals.
