GRENPRO Magnetic Parts Tray Set — 4-Pack (2×4.5" Round, 2×5.5×9.5" Rectangular), Stainless Steel with Rubber Backing

GRENPRO's 4-pack magnetic parts trays are stainless steel organizers with embedded magnets that secure small hardware to metal surfaces while protecting finishes with a soft rubber backing.

Keep fasteners, tools, and tiny components grouped and visible during repairs, builds, or maintenance. This set includes two 4.5-inch round trays and two 5.5 x 9.5-inch shallow rectangular trays, designed to resist daily workshop use with durable stainless steel and powerful magnets. The low walls make parts easy to spot and grab, while the rubberized underside prevents scratches on painted surfaces and workbenches.

How do these trays hold parts in place on different surfaces?

Each tray has embedded magnets to attach firmly to any ferrous metal surface, so trays stay put on toolboxes, vehicle panels, and metal shelving. The magnetic grip works even when the tray is mounted sideways or upside down, limiting dropped hardware during movement. For non-metal surfaces, the soft rubber backing adds non-slip stability but won’t magnetically attach.

• Embedded neodymium-style magnets for strong adhesion to steel
• Works on vertical or inverted metal panels without dropping parts
• Rubber back prevents sliding on painted or finished surfaces

What sizes are included and what kinds of parts do they hold?

The set contains two small round 4.5-inch trays and two large shallow 5.5 x 9.5-inch rectangular trays to cover a range of jobs. Small round trays are ideal for nuts, bolts, screws, and washers; the larger shallow trays suit longer fasteners, small tools, and grouped components. Shallow wall heights make everything immediately visible and reachable while minimizing the chance of parts disappearing into deep pockets.

• 2 × 4.5-inch round trays for loose small hardware
• 2 × 5.5 x 9.5-inch shallow trays for longer parts and tool bits
• Low wall design for quick access and inventory visibility

Are these trays durable enough for daily shop and field use?

Constructed from stainless steel, the trays resist corrosion and stand up to the bumps and drops common in garages and job sites. The magnets are embedded to avoid snagging and to maintain consistent holding power through repeated use. The rubber backing protects surfaces and helps the tray remain steady on smooth benches, even when nudged by tools or hands.

• Stainless steel body resists rust and everyday wear
• Embedded magnets stay secured and protected from damage
• Soft rubber backing prevents scratches and reduces sliding

How can professionals and DIYers make the most of this tray set?

Use the trays as dedicated stations for common fasteners, or mount them near your work area to catch parts during disassembly. They’re handy on service trucks, in home garages, or next to power tools to keep parts organized during multi-step jobs. Because they’re portable, you can reconfigure placement as a project progresses—attach to a toolbox, hood, lift arm or metal shelving for immediate access.

• Organize by fastener type or step in a repair process
• Mount on vehicle panels during roadside repairs or maintenance
• Keep near machines, benches, or inside parts cabinets for workflow efficiency

Who is this for: This 4-piece GRENPRO magnetic tray set suits professional mechanics, technicians, and tradespeople who need reliable, visible temporary storage for small parts, as well as hobbyists and DIY homeowners who want to avoid lost hardware during projects. If you work regularly with metal surfaces and value quick access and scratch protection, these trays offer a practical, durable solution.
