What type of fastener should be used to attach steel studs to runners?

• A. Pan head
• B. Oval head
• C. Trim head
• D. Bugle head

Answer: (A)

Choosing the right fastener head for metal framing means prioritizing a head that seats securely in steel and provides a strong, non-pulling connection between the stud and the track. A pan head screw is the best fit for attaching steel studs to runners because its broad, flat bearing surface distributes load over a larger area of metal, helping prevent pull-through and avoiding the need for countersinking. Bugle heads are designed to countersink into drywall, which isn’t ideal for metal-to-metal connections. Trim heads are low-profile and used when the fastener must be hidden, which can compromise holding power in steel framing. Oval heads don’t provide the same secure seating in thin steel as a pan head does.
