Value Collection 4.10A1BS No 10 Button Head Torx Sheet Metal Screw

Product Description

The VALUE COLLECTION 4.10A1BS is a No. 10 sheet metal screw with a button head profile and Torx T25 drive, designed for fastening thin-gauge metal assemblies in HVAC, electrical, plumbing, and general trade applications. The screw measures 1 inch in length under the head and is manufactured from Grade 18-8 stainless steel, providing solid corrosion resistance in both indoor and outdoor service environments. The Type A point allows the fastener to self-tap into sheet metal without a pre-tapped hole. At 0.01 pounds per unit, these are lightweight fasteners suited for high-volume installation work.

This screw is a standard choice for securing sheet metal panels, ductwork components, electrical enclosures, and equipment access covers. The button head profile sits low against the work surface and distributes clamping load over a wider area than a pan head, making it well-suited for applications where a flush-adjacent finish is needed. The Torx T25 drive reduces cam-out under power-tool torque, which speeds up installation when assembling multiple fasteners in sequence. Minimum order quantity is 10 units per order, sold as individual pieces per package.

Key Features

• No. 10 thread size with Type A self-tapping point for direct installation into sheet metal
• Torx T25 drive reduces cam-out compared to Phillips or slotted drives
• Button head profile provides a low-profile, wide-bearing-surface seat
• Grade 18-8 stainless steel construction for corrosion resistance in damp or outdoor environments
• 1 inch length under head suits standard sheet metal panel and enclosure thicknesses
• Inch measurement system; compatible with standard inch-system tooling and gauges

Compatibility

Designed as a general-purpose No. 10 Type A sheet metal screw for use in residential and commercial HVAC ductwork, electrical enclosures, and light sheet metal fabrication wherever a Torx T25 button head fastener is specified.

Installation Notes

Installation is performed using a T25 Torx bit with a standard electric or pneumatic screwdriver. Power down all electrical equipment and shut off HVAC or mechanical systems before accessing panels secured by these fasteners. Avoid over-torquing into thin-gauge sheet metal, as stripping the self-tapped thread will compromise the joint. Follow applicable codes such as SMACNA duct construction standards or NEC requirements for enclosure fastening where relevant.
