Key Features

• 574 Piece Assortment: Provides an extensive mix of common coarse Grade 5 hex cap screws, nuts and washers so you have fast access to multiple sizes for repairs and builds.
• Grade 5 Hardware: The coarse Grade 5 construction delivers a balance of strength and ductility suitable for automotive and light industrial uses.
• Zinc Clear Finish: Screws, nuts and washers are zinc clear plated to resist corrosion and keep parts looking consistent in exposed applications.
• Multiple Sizes: Includes 1/4in, 5/16in and 3/8in hex cap screws so you can match fasteners to common threads without having to source individual pieces.
• Organized Steel Tray: A heavy duty locking steel 24 hole compartment tray (13-3/8in wide x 2in high x 9-1/4in deep) keeps fittings sorted and portable for emergency work or on-the-job access.

Who It's For

This kit is ideal for home mechanics, hobbyists, and maintenance professionals who frequently replace or install fasteners and value having common Grade 5 sizes on hand. The assortment and durable case make it suited to garage benches, workshop drawers, and service vans where quick selection matters.

Those who need specialty fasteners, fine-thread machine screws, stainless steel corrosion resistance, or metric sizes should look elsewhere; this set focuses on coarse Grade 5 SAE hardware and does not replace specialized kits for marine or precision electronics use.
