Graph Tech LW-1440-02 Saddle-Height Screws — #4-40 × 5/16 in, 12-Pack

Best for

Replacing twelve matching #4-40 × 5/16-inch saddle-height screws in the listed Graph Tech saddle families or a fully measured compatible bridge.

Who should skip

Skip these for #4-48 or metric threads, a different required length, incompatible head/drive geometry, insufficient clearance, or an unmeasured bridge.

Watchouts

MPN is LW-1440-02 and GTIN is 702725242634. X-5/16 is a rejected truncated value. Similar-looking #4-48, metric and other-length set screws can damage threads or produce unsafe adjustment.

Likely add-ons

• saddle with verified #4-40 female thread and suitable depth
• correctly sized Allen key
• precision action/radius measuring and setup tools
• qualified guitar technician when bridge setup skills are unavailable

Verify before buying

• Is the receiving saddle threaded #4-40 rather than #4-48 or metric?
• Is 5/16-inch length correct for its thread depth and adjustment range?
• Does the set-screw head accept the available Allen key?
• Will the installed screws provide safe hand and string clearance?
• Who will complete action, radius and intonation setup?
