MS35265 part-number and dimension table

Reference sizes for identification and quotation. Availability is confirmed by inquiry; the entries do not indicate Webson stock.

Head diameter and total head height are minimum–maximum limits from the reviewed revision C. Total axial head height O includes the domed portion. It differs from the straight head-side height H listed in the detail table.

// HEAD DETAILS

Slotted drive and drilled-head details

H is the axial height of the straight head side, while O in the part table is the total axial head height. The hole diameter is nominal; the other dimensions shown here are limits. Use the full specification for drilling location, slot depth and acceptance requirements.

// LENGTH CONVENTION

Measure the correct length

Length L is measured from the bearing surface beneath the head to the tip. The length column preserves the decimal reference values in the reviewed drawing, including 0.12, 0.19 and 0.62. Total head height O is a separate axial measurement and is not included in L. Use the governing issue for length tolerances and full thread-length requirements.

// ORDERING EXAMPLES

Read the part number within its family

MS35265-17 identifies a 4-40 screw with a 0.50-inch under-head reference length. MS35265-63 is a 10-24 by 0.50-inch reference. The drilled head and slotted drive are part of the configuration; retain them in a purchasing comparison.

// MATERIAL AND CONFIGURATION

Preserve the finish and configuration

The reviewed revision C specifies carbon steel with cadmium plating to QQ-P-416, Type II, Class 3. Its part-number format is the basic MS number plus the dash number. The drilled hole is approximately perpendicular to the slot; the reviewed notes permit it to break through the bottom of the slot. Head drilling does not change the under-head length convention.
