Hillman Fasteners 42488 Stainless Exterior Trim Screw 40PK

Product Description

The HILLMAN FASTENERS 42488 is a stainless steel exterior trim screw designed for outdoor fastening applications where corrosion resistance and holding strength are critical. Sized at 1.75 inches by number 8, each screw features a self-drilling point that eliminates the need for a pilot hole in most trim and decking scenarios. The knurled shank section reduces material splitting during installation, making it well suited for finished trim work. Sold in a 40-count pack, this fastener carries a lifetime warranty and is rated to withstand 2000-hour salt spray testing, confirming its durability in coastal and high-moisture environments.

This screw is intended for exterior wood trim, fascia, siding, and similar outdoor wood-to-wood or wood-to-substrate fastening. The star drive recess provides positive bit engagement and reduces cam-out during installation. Contractors, carpenters, and skilled tradespeople working on exterior finish applications will find the self-drilling point and corrosion-resistant stainless construction appropriate for both residential and light commercial projects exposed to weather.

Installation Notes

Installation should be performed by a qualified carpenter or contractor following applicable building codes for exterior fastener requirements. Use an appropriate star drive bit to match the recess size and maintain consistent seating depth. No pilot hole is required for most trim applications, but pre-drilling may be warranted near board ends to reduce splitting risk on dense or aged lumber. Avoid overtorquing, which can strip the recess or countersink the head beyond the finished surface.
