480pc Self-Drilling Hex Washer Screws — 410 Stainless Sheet Metal Assortment
Product description
Complete assortment kit: The set contains 480 pieces divided across twelve length/size combinations. It covers two thread sizes, #8 and #10, with lengths of 1/2", 5/8", 3/4", 1", 1-1/4" and 1-1/2" for each size. Screws are sorted into labeled compartments inside a clear plastic storage case for easy selection and compact storage.
Material and construction: Each fastener is manufactured from 410 stainless steel, a high-hardness grade that provides the strength needed for self-drilling applications. The integrated hex washer head offers a wide bearing surface, eliminating the need for separate washers in many installations.
Self-drilling design: These screws feature sharp, pointed drill tips and well-formed threads that cut into thin steel, timber and composite panels without a pilot hole. Their cutting points and thread profile are intended to reduce installation time and effort on light-gauge metal and similar materials.
Compatibility and driving: Hex washer heads are sized to work efficiently with drills and impact drivers, delivering good torque transfer and consistent seating. The washer-like underside of the head helps distribute clamping force evenly when tightened.
Applications and storage: Suitable for furniture assembly, cabinet fitting, light metalwork, workshop repairs and general DIY projects both indoors and outdoors. The compact case keeps all sizes organized and ready to reach, making it convenient for home, garage or jobsite use.

VerdictThis comprehensive assortment supplies a broad range of self-drilling hex washer screws built from hard 410 stainless steel.

Good selection and reliable self-drilling action
These drove into thin metal cleanly with no pilot holes for the lighter panels I tested. The hex washer heads are easier to drive securely with an impact driver than Phillips-style screws. The threads are sharp and the 410 stainless gives the hardness required for the self-drilling tips.

Essential assortment for the workshop
I needed a one-stop collection of self-tapping screws so I wouldn’t waste time running to the store for a single size. The 480-piece kit arrived in a sturdy clear case with labeled compartments and solid latches, so sizes stayed separated during shipping. The variety solved my sizing guesswork and let me pick the exact length I needed on the spot.

Contractor-grade kit for regular jobs
As a residential contractor I appreciate a reliable assortment of fasteners. Multiple #8 and #10 sizes in one organized kit save time on site. The self-drilling points eliminate pilot holes on light materials and the hex heads pair well with cordless impact drivers. The stainless holds up well outdoors.

Clean-cut threads and expected magnetism
Thread cutting is sharp and consistent. These are 410 stainless, so they are magnetic — which I prefer for certain checks. Overall build quality is solid and the threads perform as intended in my tests.

Works great, though case dividers could be firmer
I used these to fasten stainless panels in my shop and they self-drilled as I drove them. The heads resisted stripping. My only gripe is the internal dividers aren’t fixed, so the screws shifted compartments in transit. Otherwise it’s a very handy set to keep nearby.

Perfect for outdoor metal repairs
I used the set to reattach metal roof panels and the container kept sizes easy to find while I worked on the ladder. The self-drilling tips drove straight into light steel framing with an impact driver, and the washer head seats tightly against the panels to help seal against water.

Well thought-out set with practical lengths
The kit includes both #8 and #10 in six lengths each: 1/2", 5/8", 3/4", 1", 1.25" and 1.5". The built-in washer surface under the head helps spread load without adding loose washers. Made from robust 410 stainless, the screws bite well into thin sheet, light-gauge steel, lumber and composites without pre-drilling.
