Value Collection A98171 Sheet Metal Screw Size 18 50 Pack

Product Description

The VALUE COLLECTION A98171 is a size 18 flat head sheet metal screw with a Pin In Torx drive, designed for secure fastening in sheet metal applications. Manufactured from Grade 18-8 stainless steel, this screw delivers corrosion resistance suited to both indoor and outdoor environments. The Type A point style allows for self-starting penetration into light-gauge sheet metal without a pre-drilled pilot hole. The T10 Torx drive size provides excellent torque transfer while the tamper-resistant pin-in-torx configuration resists unauthorized removal. Overall length is 1 inch. This package contains 50 screws.

This screw is used in light-gauge sheet metal assembly across HVAC, electrical enclosure, and general trade applications. The flat head countersinks flush with the workpiece surface, making it well suited for installations where a low-profile fastener is required. Licensed HVAC technicians, electricians, and sheet metal workers regularly use Type A sheet metal screws in equipment panels, ductwork flanges, junction boxes, and access door hardware. The Grade 18-8 stainless steel construction makes these appropriate for environments where mild corrosion exposure is a factor.

Compatibility

Designed as a standard Type A sheet metal screw for use in light-gauge sheet metal panels, enclosures, ductwork flanges, and similar applications where a size 18 flat head fastener with a T10 Pin In Torx drive is specified.

Installation Notes

Installation is performed with a T10 Torx bit driver; use of a pin-in-torx bit is required to engage the tamper-resistant drive recess. Power down or de-energize any electrical enclosure or HVAC equipment before fastening panels or access doors. Avoid over-driving, which can strip the sheet metal or shear the screw shank in thin-gauge material. Follow applicable codes such as NEC or SMACNA guidelines when fastening electrical enclosures or ductwork components.
