A: The GRK Fin/Trim screw can be used to in this application. Although, we would recommend using our Deck Elite screws that have been designed specifically for use in deck board applications.
A: Hi Scott, Our #8 FIN/TRIM screw has a head OD of 0.197" for more information see the engineer drawing found here: https://www.grkfasteners.com/getattachment/cbe1684f-0b30-4486-93f8-84d28879311a/Sales-Support-TRIM-RT or reach out to our customer service team at at (877) 489-2726 or email us at CS@itwbrands.com
A: Hi Bill, we recommend using the GRK RT Composite screws for any composite fastenings. The reverse thread on that product was designed to mitigate the material around the head dimpling. If you have additional questions please contact our customer service team at (877) 489-2726 or email us at CS@itwbrands.com.
A: I have used these trim head screws in MDF and never needed to predrill nor countersink for the heads. There was no "bubble up" issue where the head penetrated the MDF to contend with either. Great holding strength too.
A: YES, absolutely. Will countersink into hardwood as well.
A: Yes, they are designed to countersink and do so easily.
A: They should. You can always use a countersink bit designed for that purpose.
