// REFERENCE SIZES

MS35275 part-number and dimension table

Reference selections for identification and quotation. Webson confirms availability by inquiry; these rows do not indicate stocked inventory.

All dimensions are in inches. Printed decimal lengths such as 0.188, 0.312, 0.438 or 0.562 are retained where listed. The length tolerance column shows separate positive and negative allowances; these are not symmetric ± limits. Head dimensions are minimum–maximum drawing limits.

// MEASUREMENT GUIDE

Measure length and head geometry

L is measured from the bearing surface beneath the head to the screw tip. O is total axial head height, including the dome; H is the height of the straight head side. The head is outside the under-head length measurement.

The reviewed issue requires complete threads to within two threads of the head, or closer if practicable, for screws 2.00 inches long and shorter. Longer screws have a minimum 1.50-inch thread length. Overall screw length does not establish a fixed unthreaded grip.

// HEAD DETAILS

Check the slot and drilled head

The drilled hole is approximately at right angles to the slot and may break through the slot bottom in the reviewed drawing. The hole diameter is nominal; the head-side and slot values are minimum–maximum limits. The full issue controls drilling location, tolerances, slot depth, radii and edge treatment.

// ORDERING DETAILS

Read the complete part number

MS35275-217 is a 4-40 screw with a 0.500-inch under-head length. MS35275-263 is a 10-24 screw with the same listed length. Do not carry a dash number from the carbon-steel MS35265 family into this stainless family.

The reviewed material note permits specified corrosion-resisting steel types, including 302, 303, 304, 305, 316 and 384, with a minimum ultimate tensile strength of 80,000 psi. The family name alone does not guarantee Type 316. Preserve any specific material and certification requirement on your drawing.

// FAMILY COMPARISON

Compare related screw families

MS35276 is the stainless fine-thread drilled-fillister family. Send its full designation for review; the MS35275 coarse-thread table does not establish an MS35276 conversion.

// DRAWING REQUIREMENTS

Match the governing drawing issue

Dimensions summarize MS35275B, sheets 1–2, 14 June 1976. These are selected historical references for purchasing identification. Later amendments or notices may apply. The issue required by your drawing controls full geometry, thread, material, finish and inspection requirements. A successor standard name does not automatically authorize a part-number change or substitution.
