Straight lines make straight work. These steel line pins are forged from solid carbon steel and ground to a clean taper so they drive smoothly into joints without spalling the arris. Chrome plating adds wear resistance and helps shed mortar from the shank, making withdrawal cleaner when you move the line. On brickwork or blockwork the profile seats securely and keeps tension consistent, so your guide string stays true across the bay. Whether you’re setting out a lead, checking gauge or aligning specials, steel line pins provide the fixed points you need to place bricks confidently and keep the face running straight. Throw them in the bag—they’re small, tough and ready whenever the line needs setting.
