Quick Tip: Torque Specs for Action Screws

Published on December 14, 2022
Duration: 4:59

This expert guide, presented by Steven Caleb of Brownells, details the critical importance of using correct torque specifications for firearm action screws. The appropriate torque is dictated by the stock material, not the action itself. Different materials like synthetic with metal bedding, unbedded wood, and cheaper synthetics require distinct torque ranges to prevent damage and maintain accuracy. Always consult manufacturer specifications or use conservative estimates for unknown materials.

Quick Summary

The correct torque specification for rifle action screws depends entirely on the stock material, not the action. Synthetic stocks with metal bedding can handle higher torque (60-65 in-lbs), while wood stocks require less (30-35 in-lbs). Over-torquing can damage the stock and reduce accuracy.

Frequently Asked Questions

What determines the correct torque specification for rifle action screws?

The correct torque specification for rifle action screws is determined by the material and construction of the rifle stock, not the action itself. Different materials like wood, synthetic, or those with metal bedding blocks have varying tolerances for compression and stress.

What are typical torque ranges for different rifle stock types?

Synthetic stocks with metal pillars or bedding blocks can often be torqued to 60-65 inch-pounds. Traditional wooden stocks typically require lower torque, around 30-35 inch-pounds. Cheaper synthetics or unknown materials should default to the lower wood stock range.

What happens if you over-torque rifle action screws?

Over-torquing action screws can damage the stock, leading to a loss of accuracy. On some actions like Savage, it can cause the action to lock up. For rimfires, it can cause undue flex.

How can I find the correct torque spec for my rifle's action screws?

The best way to find the correct torque spec is to consult the manufacturer of the rifle stock or the firearm itself. If specifications are unavailable, use conservative torque values based on the stock material.
