Shipping calculated at checkout
Supplied in a production-ready carton of 250, these 0.275 x 7-7/8 Simpson Strong-Drive® SDCP TIMBER-CP screws are the contractor's choice for multi-layer mass timber slabs, glulam beams, and structural heavy framing. Each fastener is forged from high-strength case-hardened alloy carbon steel treated with an electro-deposited yellow zinc coating to protect against interior oxidation. The non-slip T40 6-lobe head design and underhead countersinking ribs provide clean surface seating and exceptional clamping force without pre-drilling in most species.
