From the maker · Hillman’s description
Heavy-duty Grade 8 hex cap screws built from heat-treated steel for high-strength fastening. The 5/8 in. diameter, 2-1/2 in. length bolts feature coarse threads and a washer face under the head for a secure, durable hold in structural applications.
Industrial Strength, Clean Hardware Presence
These Grade 8 hex cap screws bring a crisp, utilitarian polish to exposed fastener moments. The bold head and warm yellow dichromate finish create a subtle accent against raw woods and dark metals. Try them on open shelving brackets or custom fixtures where hardware becomes part of the story. It’s a small detail that telegraphs strength—and luxury—in every turn.
Secure your build with Grade 8 reliability—add this 25-pack to your cart today.
