Pro Products PS8-34MSD Hex Head Self-drilling Screw

Product Description

The PRO PRODUCTS PS8-34MSD is a No. 8 drill point self-drilling screw with a 1/4 inch hex head and a 3/4 inch length. Self-drilling screws of this type combine the drilling and fastening steps into a single operation, eliminating the need for a pre-drilled pilot hole. The hex head drive allows for positive socket engagement during installation, reducing cam-out. This fastener is commonly installed by HVAC technicians, sheet metal fabricators, electricians, and general trade contractors working with light-gauge metal assemblies.

This screw is suited for light-gauge sheet metal applications including HVAC ductwork, equipment enclosures, electrical panels, and metal framing. The No. 8 drill point designation indicates the fastener is engineered to penetrate standard sheet metal gauges without pre-drilling. The 3/4 inch length keeps the fastener appropriate for thin-material joints where a longer screw would risk interference or blow-through on the back side of the assembly.

Key Features

• 1/4 inch hex head for use with standard hex socket drivers and nut drivers
• No. 8 drill point tip drills its own pilot hole in light-gauge sheet metal
• 3/4 inch length suited for thin-material and single-layer sheet metal joints
• Single-step fastening eliminates separate drilling and tapping operations
• Hex drive engagement reduces cam-out compared to slotted or Phillips head fasteners

Compatibility

Designed as an OEM-style replacement fastener for light-gauge sheet metal assemblies typical in HVAC, electrical, and general sheet metal construction applications.

Installation Notes

Install using a standard 1/4 inch hex nut driver or hex socket attachment on a power drill or impact driver. Set clutch or torque settings appropriately to avoid overdriving and stripping the screw head or distorting thin sheet metal. Ensure material thickness is within the rated range for a No. 8 drill point to achieve full thread engagement. Always follow applicable local codes and manufacturer assembly specifications when fastening equipment enclosures or ductwork.
