The best choice depends on whether you need a specific trilobular thread form or a general self-tapping screw assortment. The products below are 410 stainless steel self-tapping or self-drilling screws in several head styles and size ranges; the supplied product details do not confirm a trilobular thread design. Choose the Wensilon pack for a single truss-head size, the VGBUY kit for #8 screw lengths, or the Taiss kit for the broadest size range.

450-Piece 410 Stainless Steel Hex-Head Assortment
This kit includes #8 and #10 screws in five lengths, from 1/2 inch to 1-1/4 inches. Its hex-head format makes it a practical option when a project calls for hex-head sheet metal screws and several lengths in one assortment. The listed features describe 410 stainless steel, sharp tips, and clean threads.
Best for: DIYers and repair projects that use common #8 and #10 sizes. It was selected for its range of lengths and two screw diameters. Keep in mind: 410 stainless steel is magnetic, and the product details do not identify these screws as trilobular.
Wensilon 300-Piece #8 Truss-Head Screws
Wensilon’s pack contains 300 #8 x 3/4-inch truss-head self-tapping screws made from 410 stainless steel. The product description highlights deep threads and holding power for nonmetallic or soft-metal materials. It says the screws can be driven directly into a product without installation holes, depending on the application.
Best for: Buyers who need many screws in one specified size and prefer a truss head. It is included for its focused quantity and stated general-purpose use. Keep in mind: This pack offers only one listed size, so it is less flexible when a project requires multiple diameters or lengths. The listing does not confirm a trilobular thread form.
450-Piece Truss-Head Assortment for Metal
This assortment provides #8 and #10 truss-head screws in five lengths from 1/2 inch to 1-1/4 inches. Its listed material is 410 stainless steel, and the description calls out sharp tips and precisely formed threads. The assortment is similar in size range to the hex-head kit above, but uses a truss-head style.
Best for: Projects that need a selection of #8 and #10 truss-head screws rather than hex heads. It was selected because it combines two diameters with multiple lengths. Keep in mind: The product details say 410 stainless steel is magnetic. They do not specify a trilobular thread profile, so verify thread form separately if that is essential.
Taiss 1,000-Piece Multi-Size Screw Kit
Taiss lists 1,000 self-tapping screws in #8, #10, #12, and #14 sizes, with lengths from 1/2 inch to 2 inches across 16 size combinations. The screws include rubber washers, and the kit comes in a portable hand box. The stated uses include furniture repair, machinery, construction, assembly, and DIY fastening.
Best for: Buyers who need more diameter and length options than a basic #8/#10 assortment provides. It was selected for its broad range and storage case. Keep in mind: The listing identifies the material as magnetic 410 stainless steel and does not establish that the thread shape is trilobular.
VGBUY 180-Piece #8 Truss-Head Kit
This 180-piece kit contains #8 screws in six lengths, from 1/2 inch to 1-1/2 inches. The listing describes a drill-bit-shaped tip intended to help the screws penetrate without a pilot hole and names metal-to-metal and metal-to-wood connections as uses. The screws are made from 410 stainless steel.
Best for: Projects that use #8 screws but need several lengths and a modified truss head. It was selected as a smaller, focused alternative to the larger mixed-diameter assortments. Keep in mind: It does not include #10 or larger diameters, and the product details do not specify a trilobular thread form.
Buying Guide: How to Choose the Right Screws
Do you specifically need a trilobular thread?
Check the product specifications for an explicit trilobular or three-lobed thread description. “Self-tapping” describes a screw’s ability to form or cut threads as it is installed; “self-drilling” commonly refers to a drill-shaped tip. Neither term alone confirms a trilobular profile. The five listings here describe self-tapping or self-drilling screws, but do not establish that feature.
Which head style and size should you choose?
Match the head style to the project’s access and bearing needs, and follow the fastener requirements for the material being joined. The two 450-piece assortments offer both #8 and #10 sizes. The Taiss kit adds #12 and #14, while the VGBUY and Wensilon options focus on #8 screws. Compare the listed lengths with the material thickness and required engagement.
Does 410 stainless steel suit your application?
All five products list 410 stainless steel. The descriptions emphasize strength and corrosion resistance, but do not provide a specific environmental rating. The listings also note that 410 stainless steel is magnetic. For demanding or corrosive environments, confirm material suitability with the project specification rather than relying on a general stainless-steel label.
Should you choose an assortment or one size?
A mixed assortment is useful when you expect to work with different thicknesses or screw lengths. A single-size pack such as Wensilon’s can suit a repeated task where the required size is already known. Check the package quantities for each size before ordering, especially when a project requires a particular length in bulk.
